For a large, top-rated corporation, 97% of employees said the corporation is a great place to work. Suppose that we will take a random sample of 7 employees. Let p represent the proportion of employees from the sample who said the corporation is a great place to work. Consider the sampling distribution of the sample proportion p.Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed.(a)Find μp (the mean of the sampling distribution of the sample proportion).=μp (b)Find σp (the standard deviation of the sampling distribution of the sample proportion).=σp

There is a very popular lottery in which a ticket is called a scratcher. In this lottery, 49% of the scratchers are winning ones. Suppose that we will take a random sample of 8 scratchers. Let p represent the proportion of winning scratchers from the sample. Consider the sampling distribution of the sample proportion p.Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed.(a)Find μp (the mean of the sampling distribution of the sample proportion).=μp (b)Find σp (the standard deviation of the sampling distribution of the sample proportion).=σp

A large airline company called Cloudscape Co. monitors customer satisfaction by asking customers to rate their experience as a 1, 2, 3, 4, or 5, where a rating of 1 means "very poor" and 5 means "very good". The customers' ratings have a population mean of =μ4.60, with a population standard deviation of =σ1.94. Suppose that we will take a random sample of =n10 customers' ratings. Let x represent the sample mean of the 10 customers' ratings. Consider the sampling distribution of the sample mean x.Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed.(a)Find μx (the mean of the sampling distribution of the sample mean).=μx (b)Find σx (the standard deviation of the sampling distribution of the sample mean).=σx

A simple random sample of size 300 was taken from the population of all manufacturing establishments in a certain state: 11 establishments in the sample had 100 employees or more. Estimate the percentage of manufacturing establishments with 100 employees or more.5 Attach a standard error to the estimate.

The CEO of a company wants to estimate the percent of employees that use company computers to go on Facebook during work hours with 95% confidence. He selects a random sample of 150 of the employees and finds that 53 of them logged onto Facebook that day. What is the estimate of the standard error of the proportion ?

Suppose the population of all public Universities shows the annual parking fee per student is \$110 with a standard deviation of \$18. If a random sample of size 49 is drawn from the population, the probability of drawing a sample with a sample mean between \$100 and \$115 is?Select one:a.0.9738.b.0.4738.c.0.0262.d.0.6103.e.0.1103.
