Question

A newly hired telemarketer is told he will probably make a sale on about 12% of his phone calls. The first week he called 150 people, but only made 15 sales. Should he suspect he was misled about the true success rate? Explain. Choose the correct answer below. Fifteen sales is more than 3.0 SDs below the mean. He was probably misled. Fifteen sales is more than 30 SDs below the mean. He was probably not misled. Fifteen sales is less than 1.0 SDs below the mean. He was probably not misled. Fifteen sales is more than 0.5 SDs below the mean. He was probably misled.

Answer 1

The telemarketer may have been misled about the true success rate because the actual number of sales is less than the expected number of sales.

Step-by-step explanation:

To determine if the telemarketer should suspect he was misled about the true success rate, we can calculate the expected number of sales he should have made based on the given success rate.

Expected number of sales = number of phone calls * success rate

Expected number of sales = 150 * 0.12 = 18

Since the actual number of sales (15) is less than the expected number of sales (18), it suggests that the telemarketer may have been misled about the true success rate.
