Question

Lily, a pharmacist, would like to test the claim that the mean weight of prescriptions is 2.5oz. She tests this claim by recording the weight of 45 prescriptions that she randomly selected from recent customer prescription orders. The following is the data from this study:

a. One-sample t-test
b. Chi-squared test
c. Paired t-test
d. Two-sample t-test

Answer 1

The appropriate test to use in this scenario is a one-sample t-test. Lily should use this test to determine if the mean weight of prescriptions differs significantly from the claimed population mean of 2.5oz.

Step-by-step explanation:

The appropriate test to use in this scenario is a one-sample t-test. The one-sample t-test is used when comparing the mean of a sample to a known population mean, which is the case here. Lily wants to test the claim that the mean weight of prescriptions is 2.5oz, so she would use a one-sample t-test to determine if the sample mean differs significantly from the claimed population mean.
