Among iPhone users who share their data with Apple, the weekly screen time is skewed to the right with = 13.5 hours and = 3.75 hours. A random sample of 100 iPhone users are selected and the mean weekly screen time (x) of the sample is calculated.

1. Describe the shape of the sampling distribution of x for samples of 100 randomly selected iPhone users. Justify your answer.

1. Find the mean and standard deviation of the sampling distribution of x. Be sure to check the 10% condition.

1. Calculate the probability that the weekly screen time for the sample is between 12 and 13 hours.
