Question
A researcher wishes to test the efficacy of three different weight loss programs. after two weeks of following the programs. Random independent samples of participants
A researcher wishes to test the efficacy of three different weight loss programs. after two weeks of following the programs.
Random independent samples of participants in each program are taken with their net weight losses (in pounds) recorded.
Assume participants follow the programs throughout the duration of the 2-week program period. Assume that the
populations from which these samples are drawn are normally distributed. Run Levene's Test for Homogeneity to test the
equal variances assumption required to run a One-Way ANOVA. Show all work (If you use any technology in your solution
(TI-84, excel, SPSS, minitab, etc...), cite when/where.). State the null and alternative hypothesis for this test. Compute the
associated test statistic for this test. Based on the result obtained from Levene's Test, is a One-Way ANOVA applicable to test
for different population mean weight losses from these programs after two weeks participation (explain)? If YES, then
perform a One-Way ANOVA and show ALL associated work from the statement of the null and alternative hypotheses to
the conclusion of the One-Way ANOVA. If NO, state that One-Way ANOVA is not applicable.
2) The data below represent the weight losses for people on three different programs.
