Assume that a sample is used to estimate a population proportion p. Find the margin of error E (or EBP) that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places. 95% confidence, n= 320, X = 60

Use the given data to find the minimum sample size required to estimate the population proportion.

a. Margin of error: 0.004; confidence level: 95%; p and q unknown.
b. Margin of error: 0,009; confidence level: 99%; P and unknown
c. Margin of error: 0.01; confidence level: 95%; from a prior study, p is estimated by the decimal equivalent of 52%

Find the y-intercept and x-intercept for the equation 5x-3y=60 what is the y-intercept

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
