Answer 1

The approximate average hold time for all customers calling the customer service department is calculated by finding the average of the hold times in the provided data set.

Step-by-step explanation:

The manager of the customer service department of an e-commerce company wishes to calculate the approximate hold time for all customers who call the department, using a sample data set of the hold time in minutes for 10 calls picked at random.

To find the average hold time for all customers, one should calculate the mean of the hold times in the data set. This involves adding up all the hold times provided and then dividing that sum by the number of calls in the data set. Thus, the correct answer is: the average of the hold times in the data set (Option b).
