there is no prior information about the proportion of americans who support gun control in 2019. if we want to estimate 97% confidence interval for the true proportion of americans who support gun control in 2019 with a 0.27 margin of error, how many randomly selected americans must be surveyed?

The Poisson distribution is a probability distribution that describes the number of independent occurrences of an event in a fixed interval of time or space.

In this case, the random variable is the number of occurrences during an interval. Therefore, the statement "the random variable is the number of occurrences during an interval" applies to the Poisson distribution. Another statement that applies to the Poisson distribution is "the probability of the event is proportional to the interval size". This means that the probability of observing k events in a fixed interval is proportional to the length of the interval. However, the statement "the probability of an individual event occurring is quite large" does not describe the Poisson distribution. In fact, the Poisson distribution assumes that the probability of an individual event occurring is small, but the number of events is large. Finally, the statement "the intervals do not overlap and are independent" is not a defining characteristic of the Poisson distribution, although it is often assumed in practical applications. In summary, the Poisson distribution is a probability distribution that models the number of independent occurrences of an event in a fixed interval. The probability of the event is proportional to the interval size, and the random variable is the number of occurrences during an interval.

4.1 The daily rate of order delivery is 16 orders.

4.2 On average, there will be 0.75 orders awaiting prep at any point in time at this grocery store.

4.1 Given that each order takes 30 minutes to deliver, we can calculate the number of orders delivered per hour:

Number of orders delivered per hour = 60 minutes / 30 minutes per order = 2 orders per hour

Number of orders delivered per day = Number of orders delivered per hour * Number of hours in a workday

Number of orders delivered per day = 2 orders per hour * 8 hours

= 16 orders per day

4-2. Given that orders are received at a rate of 3 per hour and each order requires 15 minutes of prep time, we can calculate the average number of orders awaiting prep at any point in time.

Average number of orders awaiting prep = (Arrival rate * Prep time) / 60

Average number of orders awaiting prep = (3 orders per hour * 15 minutes) / 60 minutes

= 0.75 orders

Answer:

w = 28 miles

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides.

The sum of the lengths of the sides is w + 28 + 28.

The perimeter is 84.

w + 28 + 28 must equal 84.

w + 28 + 28 = 84

Now we solve for w.

Add 28 and 28.

w + 56 = 84

Subtract 56 from both sides.

w = 28

Answer: D) 15.7

Step-by-step explanation:

Start with the formula C=2 πr

Then solve for r r=C2π = 98.62·π = 15.69(7)204

The radius of the circle is 15.7 mm.

The route or boundary that encircles any shape in mathematics is defined by the shape's circumference.

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area. The length of a straight line drawn from the centre of a circle equals the diameter of that circle.

We have,

The circumference of Circle = 2πr

Also, The circumference of a circle is 98.596 millimeters.

So, circumference of Circle = 2πr

98.596 = 2πr

98.596 = 6.28r

r= 98. 596 / 6.28

r = 15.7 mm

Thus, the radius is 15.7 mm.

At steady state conditions, the temperature distribution in a large thin plate with uniform surface temperature will be parabolic. This is due to the fact that heat flows from hotter regions towards colder regions until the temperature across the entire plate reaches equilibrium.

In other words, the temperature distribution throughout the plate will be such that the rate of heat transfer at any point within the plate is equal to the rate of heat transfer at any other point within the plate.

The parabolic temperature distribution can be mathematically represented by an equation of the form T(x,y) = T0 - (Q/4k)(x^2 + y^2), where T0 is the uniform surface temperature of the plate, Q is the rate of heat input per unit area, k is the thermal conductivity of the material, and x and y are the distances from the center of the plate in the two orthogonal directions.

This equation shows that the temperature distribution is parabolic, with the highest temperature at the center of the plate and decreasing temperatures towards the edges. This type of temperature distribution is commonly observed in many engineering applications involving heat transfer in thin plates, such as in electronics cooling or in the design of heat exchangers.

Since the calculated test statistic (2.836) is greater than the critical value (1.645), we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis that more than half of internet users have posted photos or videos online.

To test the hypothesis that more than half of internet users have posted photos or videos online, we can use a one-sample proportion test. Let p be the true proportion of internet users who have posted photos or videos online. The null and alternative hypotheses are:

H0: p <= 0.5

Ha: p > 0.5

We will use a significance level of 0.05.

Using the given information, we have:

n = 855

x = (56/100) * 855

= 479.6 (rounded to nearest whole number, 480)

The sample proportion is:

p-hat = x/n

= 480/855

= 0.561

The test statistic is:

z = (p-hat - p0) / √(p0 * (1 - p0) / n)

where p0 is the null proportion under the null hypothesis. We will use p0 = 0.5.

z = (0.561 - 0.5) / √(0.5 * (1 - 0.5) / 855)

= 2.836

Using a standard normal distribution table or calculator, the critical value for a one-tailed test at a 0.05 level of significance is approximately 1.645.

This represents the proportion of phishing attempts in your sample data, while the remaining 1 - 0.225 = 0.775 represents the proportion of non-phishing attempts.

To find the center of the confidence interval for this survey data, you'll want to use the sample proportion (p-hat). Here's a step-by-step explanation:

1. Determine the sample size (n): There are 80 sample values in the survey.

2. Calculate the number of phishing attempts: 23% of 80 is phishing attempts. To find this value, multiply 0.23 by 80: (0.23 * 80) = 18.4. Since we can't have a fraction of an attempt, round to the nearest whole number: 18 phishing attempts.

3. Calculate the sample proportion (p-hat): Divide the number of phishing attempts (18) by the sample size (80): (18 / 80) = 0.225.

So, the value you should use for the center of the confidence interval related to this data is the sample proportion, p-hat = 0.225. This represents the proportion of phishing attempts in your sample data, while the remaining 1 - 0.225 = 0.775 represents the proportion of non-phishing attempts.

Step-by-step explanation:

Since you bring 12 items for 4 dinners, you have a total of 12 items to choose from.

For the first dinner, you need to choose 3 items out of the 12. You can do this in:

12 choose 3 = (12!)/(3!*(12-3)!) = 220 ways

For the second dinner, you have used up 3 items in the first dinner, so you have 9 items left to choose from. You need to choose 3 items out of the 9. You can do this in:

9 choose 3 = (9!)/(3!*(9-3)!) = 84 ways

For the third dinner, you have already used up 6 items, so you have 6 items left to choose from. You need to choose 3 items out of the 6. You can do this in:

6 choose 3 = (6!)/(3!*(6-3)!) = 20 ways

For the fourth dinner, you have already used up 9 items, so you have only 3 items left to choose from. You need to choose all 3 items. You can do this in:

3 choose 3 = (3!)/(3!*(3-3)!) = 1 way

Therefore, you can choose items for the first dinner in 220 ways, for the second dinner in 84 ways, for the third dinner in 20 ways, and for the fourth dinner in 1 way.
