participants on this popular weight loss programme.
State the null and the alternative hypotheses for this test.
Determine the missing value ‘∗’.
Use the tables provided to approximate the missing value ‘∗∗’.
![5. It is claimed that participants of a popular weight loss programme have a mean weight loss
of 10 pounds after 1 month. A medical researcher randomly selected 30 participants of the
programme and recorded their weight loss (in pounds) after 1 month. The data was inputted
into MINITAB for analysis. Exhibit 1, below, was subsequently generated.
