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. Test of mu- 10 vs < 10 The assumed standard deviation = 2.5 Variable Weight Loss N Exhibit 1 One-Sample Z: Weight Loss 30 Mean 8.977 StDev 2.463 SE Mean ?
