Question

Write the word or phrase that best completes each statement or answers the question. Perform the indicated goodness-of-fit test. In studying the occurrence of genetic characteristics, the following sample data were obtained. At the 0.05 significance level, test the claim that the characteristics occur with the same frequency. Test the claim that the samples come from populations with the same mean. Assume that the populations are normally distributed with the same variance. The data below represent the weight losses for people on three different exercise programs. At the 1% significance level, does it appear that a difference exists in the true mean weight loss produced by the three exercise programs?

Explanation / Answer

1)applying chi square goodness of fit on above data:

for above test stat 8.2632 , p value =0.1423

as p value is greater then 0.05 level we can claim that charecteristics occur with same frequency.

2)

applying one way ANOVA on above:

as p value is greater then 0.05 level of signficance we can not reject that there is no differnece exist in the true mean weight loss produced by the three excercise programmes.
