A market researcher for a consumer electronics company wants to study the media viewing behavior of residents of a particular area. A random sample of 70 respondents is selected, and each respondent is instructed to keep a detailed record of time spent engaged viewing content across all screens in a particular week. The results are as follows: Content viewing time per week: X=53 hours, S=3.8 hours. 21 respondents have high definition (HD) on at least one television set. Complete parts (a) through (e) below. a. Construct a 99% confidence interval estimate for the mean content viewing time per week in this area. nothing≤μ≤nothing (Round to two decimal places as needed.) b. Construct a 99% confidence interval estimate for the population proportion of residents who have HD on at least one television set. nothing≤π≤nothing (Round to four decimal places as needed.) c. Suppose that the market researcher wants to take another survey in a different location. What sample size is required to be 99% confident of estimating the population mean content viewing time to within ±2 hours assuming that the population standard deviation is equal to 4 hours? nothing (Type a whole number.) d. How many respondents need to be selected to be 99% confident of being within ±0.07 of the population proportion who have HD on at least one television set if no previous estimate is available? (Type a whole number.) e. Based on (c) and (d), how many respondents should the market researcher select if a single survey is being conducted? nothing (Type a whole number.)

For the following problems: a) Identify the null and alternative hypothesis. b) Calculate the critical value c) Calculate the test statistic d) Draw your conclusion on whether the null hypothesis will be rejected or failed to be rejected. e) Find the 95% Confidence Interval 1. According to work done by Nick Wilson of Otago University Wellington, the proportion of individuals who cover their mouths when sneezing is 0.733. As part of a school project, Mary decides to confirm this by observing 100 randomly selected individuals sneeze and finds that 78 covered their mouth when sneezing. Test to see if there is a difference in proportions of people covering their mouth when sneezing. Let α=0.05.
