However: you are Interested In measuring how TIkTok usage compares between individuals in their 20s and Individuals In their me. Let p, represent the population proportion ofAmerican adults ages 20-29 who use 'IikTok. whlle p2 represents the population proportion ofAmerican adults ages 30-39 who use TIkTok. To estimate the difference in the population proportion p, - pm a random sample of 320 American adults ages 20-29 and a random sample of 412 American adults ages 30-39 were selected and asked If they use TIkTok. We used Fl to construct a 99% confidence Interval to estimate p, - p2: Stilt [1] "The 99% com'idence interval is given as: (-6.9?6?, 63336)."

[:1 No, because. based on the 99% condence Interval, (J is a reasonable value for the unknown population parameter p1 - pg. [:1 Yes, because the confidence Interval was constructed using on results from large random samples. 5.d 1 pol ntis] A 95% condence Interval based on the same date would result In an Interval that Is the 99% confidence Interval. | I. | C] wider than C] narrower than [:1 the same width as
