Exercise 1Emma reads that the average age of graduate students is 21 years old. Shewanied to estimate the mean age of the graduate students at SKY University,so she took a random sample of 30 graduate students. She found that theirmean age was 20.8 at 95% confidence level with 1.54 margin of error.Guide Questions:1. What is the lower limit?2. What is the upper limit?3. What is the confidence interval?4. Based on the interval you get, is it plausible that the mean age of allgraduate students at their university is also 21 years?

Given that The average age of graduate students is 21 years old. Random sample size (n) = 30 Mean…

Answered: Exercise 1 Emma reads that the average…

Suppose that you wanted to know if the percentage of people who will attend a sporting event this year will decrease. Last year, 43% of Americans attended a sporting event. After taking a sample, you attain a sample percentage of 18% with a margin of error of 3%. Construct a confidence interval and use that interval to determine if the number of Americans who will attend a sporting event has decreased. Show your calculation for the interval and then state your conclusion in complete sentences.
