A salesman makes 40 calls per week. People complained because they said that estimate was to low. In a random sample of 28 people, the standard deviation was computed to be 2.1 calls at the the significant level .05. Can one conclude that more than 40 calls were made on average?© BrainMass Inc. brainmass.com June 3, 2020, 9:07 pm ad1c9bdddf
Step 1: State the Null Hypothesis (H0) and the Alternate Hypothesis (H1)
H0: M less than or equal to 40
H1: M> 40
Step 2: Select a Level of Significance
This is a one-tailed test. The significant level is .05.
This solution provides an answer to a question using five step hypothesis testing.
