QUESTION 6A company owns 520 cars and the manager wants to estimate the mean distance traveled during the past 30 working days. So he gathered theinformation for 36 cars. Assuming the distances traveled are normally distributed. Find the corresponding critical value for calculating a 97%confidence interval. Round your answer to three decimal places if needed.

given data,N=520 carsdata are normally distributed n=36df=n-1=36-1=35CI=97%α=1-0.97=0.03

QUESTION 23 Ali constructed a 98% confidence interval for the mean amount spent per day in a shopping mall based on 100 customers. The confidence interval was found to be (AED 1150, AED 2150). Select all correct answers. The mean amount spent per day by the 100 customers selected in the sample falls between AED 1150 and AED 2150. We are 98% confident that the mean amount spent per day by customers falls between AED 1150 and AED 2150. The mean amount spent per day by all customers falls between AED 1150 and AED 2150. 98% of all customers spent between AED 1150 and AED 2150 per day.
