Confidence Interval question

The average amount of time, in minutes, for students to complete a standardized test is normally distributed. A data analyst takes a sample of n = 37 student times and finds a 90% confidence interval to be [130.1, 163.9]. What is the population parameter? Pick C What is the interpretation of the confidence interval? Pick 10% confidence exists that the average time taken on the test is between 130.1 and 163.9. 90% confidence exists that the average time taken on the test is between 130.1 and 163.9. 90% of the sample data falls between 130.1 and 163.9. 90% of the students will take between 130.1 and 163.9 minutes to complete the test.The average amount of time, in minutes, for students to complete a standardized test is normally distributed. A data analyst takes a sample of n = 37 student times and finds a 90% confidence interval to be [130.1, 163.9] What is the population parameter? Pick The average amount of time taken on the test by all students The average amount of time taken on the test by the sample of 37 students The sample size n = 37 PICK
