A market researcher for a consumer electronics company wants to study the media viewing behavior of residence of a particular area. A random sample of 40 respondents is selected and each respondent is instructed to keep a detailed Record of time spent in gaged doing contact across all screens in a particular week. The results are as follows:continuing time per week: x=54 hours, s=4.1 hours. 8 respondents have high definition on at least one television set. hour assuming that the population standard deviation is equal to 5 hours?(Type a whole number.)d. How many respondents need to be selected to be 90% confident of being within ±0.09 of the population proportion who have HD on at least one tele(Type a whole number.)e.
