A dietician is researching two new weight gain supplements that have just hit the market: Ripped and Gainz. She wants to determine if there is any difference between the two supplements in the mean amount of weight gained (in kg) by the people who take them.

Transcribed Image Text:A dietician is researching two new weight gain supplements that have just hit the market: Ripped and Gainz. She wants to
determine if there is any difference between the two supplements in the mean amount of weight gained (in kg) by the people
who take them.
The dietician tracks the total weight gain (in kg) over a year of a random sample of 14 people taking Ripped and a random
sample of 12 people taking Gainz. (These samples are chosen independently.) These data are shown in the table.
Total weight gains (in kg)
Ripped
Gainz
14.1, 10.9, 12.1, 5.2, 12.0, 17.1, 9.0, 14.8, 11.2, 6.8, 12.4, 8.5, 12.1, 10.5

Send data to Excel
Assume that the two populations of weight gains are approximately normally distributed. Can the dietician conclude, at the
0.05 level of significance, that there is a difference between the population mean of the weights gained by people taking
Ripped and the population mean of the weights gained by people taking Gainz?
Perform a two-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places: (If necessary, consult a list of formulas.)
(a) State the null hypothesis Ho and the alternate hypothesis H₁.
Ho
H₁O
(b) Determine the type of test statistic to use.
(Choose one) ▼
(c) Find the value of the test statistic. (Round to three or more decimal places.)
0
(d) Find the p-value. (Round to three or more decimal places.)
0
(e) At the 0.05 level of significance, can the dietician conclude that there is a
difference between the mean weight gained by people taking Ripped and
