8. Use the values on the number line to find the sampling error.   An infinite number line, labeled from 23 to 26, has tick marks in increments of 0.5. Labeled points are plotted at mu equals 23.78 and x overbar equals 25.58.           23242526 x=25.58 μ=23.78       Question content area bottom Part 1 The sampling error is enter your response here

Describe the sampling distribution of p. Round to three decimal places when necessary.   N=22,000​, n=400​, p=0.3

Use the expression in the accompanying discussion of sample size to find the size of each sample if you want to estimate the difference between proportions of men and women who own smartphones assume that you want 99% confidence that your area is no more than 0.045

= 12,000 and p = 0.71. A random sample of 902 elements selected from this population gave p 0.61. Find For a population, N the sampling error. Enter the exact answer. sampling error =

Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places.95% confidence; n = 333, x = 54

Some states now allow online gambling. As a marketing manager for a casino, you need to determine the percentage of adults in those states who gamble online. How many adults must you survey in order to be 90% confident that your estimate is in error by no more than one percentage point? Complete parts (a) and (b) below. a. Assume that nothing is known about the percentage of adults who gamble online. n=0 (Round up to the nearest integer.) b. Assume that 18% of all adults gamble online. n= (Round up to the nearest integer.)
