please answer

A shopper's time spent at the Target located in the University Town Center is right-skewed with mean 15 minutes and standard deviation 5 minutes. Suppose we take a random sample of 100 shoppers and measure their shopping times. For the sample of 100 shoppers, what is the sampling distribution for the average time spent Select shopping at Target? AN(15,0.5) N(15,0.5) AN(0,0.5) N(0,1) What is the probability that the mean shopping time of the sample is between 16 and 20 minutes? [ Select ] 0.9772 0.6112 0.0228 0.356 What is the probability that the mean shopping time of the sample is less than 14.5 minutes Select 0.8413 0.1587 0.1015 0.4844 [Select ] What is the average shopping time at the 35th percentile? 15.34 14.15 15.13 14.81 Suppose our sample was only 20 shoppers. Could you still use the central limit theorem? [ Select ] Yes No
