In a random sample of 116 people from a small university, it was found that their posts on Snapstagram had an average of 627 likes. Construct a 93% confidence interval to estimate the number of likes for the students at the university. Assume the population standard deviation is 100 likes. Round z-scores to two decimal palces for intermediate calculations. a. Which parameter are you estimating? Select an answer v b. What is the point estimate? Select an answer = c. Check all of the requirements that are satisfied. O random O the I distribution is normal since n > 30 O the I distribution is normal since the x distribution is normal O the p distribution is normal since np > 10 and nq > 10 d. Find the margin of error. Round to three decimal places. E = e. Give the confidence interval in interval notation: (lower bound, upper bound). Round to one decimal places. f. Select the correct conclusion. OWe are 93% confident that the average number of likes on all students' Snapstagrams posts is between the two numbers found. O We are 93% confident that the average number of likes on the sample of students Snapstagrams posts is between the two numbers found. We are 93% confident that the number of students that use Snapstagram is between the two numbers found. We are 93% confident that the number of Snapstagram users is between the two numbers found
