Answer the given problem. Use the steps in hypothesis testing when presenting the results.
A health researcher is interested in comparing 3 methods of weight loss: low calorie diet, low fat diet and high exercise regimen. He selected 15 moderately overweight subjects and randomly assigned 5 to each weight-loss program. The following weight reductions (in lbs) were observed after a one-month period. Test the hypothesis that the extent of weight reduction does not differ by type of weight-loss program.
Low Fat : 7 7 5 4 6
Low Calorie : 7 8 8 9 5
High Exercise Regimen : 7 9 7 8 8
The Department of Motor Safety is conducting a study to determine how many hours each weekcar and truck drivers drive. In order to assess this, they equipped special trackers in 50 cars andtrucks. They received the following information:
Truck Drivers Car DriversX̄ = 19.5s = 4.75n = 50
X̄ = 17s = 3.5n = 501. What is the null and research hypothesis for this study?
A randc v ection of volunteers at a research institute have been exposed to a typical cold virus. After they started to have cold symptoms, 15 of them were
given multivitamin tablets daily which contain 3 grams of vitamin C and various other vitamins and minerals. The remaining 15 volunteers were given placebo
tablets. For each individual, the length of time taken to recover from cold is recorded. At the end of the experiment following data are obtained:
Days to recover from cold
Treated with multivitamin 3.0, 3.2, 6.3, 3.8, 5.8, 7.3, 5.3, 5.7, 7.9, 5.7, 6.2, 4.3, 3.8, 6.1, 4.6
Treated with placebo
7.1, 5.9, 5.5, 5.2, 2.4, 3.7, 4.9, 3.5, 4.3, 6.6, 4.5, 3.2, 3.4, 4.1, 2.9
Send data to calculator v
It is known that the population standard deviation of recovery time from cold is 1.8 days when treated with multivitamin, and the population standard deviation
of recovery time from cold is 1.5 days when treated with placebo tablets. It is also known that both populations are approximately…
