Use the following data sets: Group A (50,43,55,62,57), Group B (49,51,56,53,47), Group C (59,51,46,55,49) and group D (47,55,49,49,53).

Each member need to use the group data samples of each population of any variable and determine which one has a lower average with an alpha of 5%.

Solutions

Expert Solution

Group B has a lower average with an alpha of 5%

Run Anova single factor analysis to find there is any differences in the mean value of groups

P-value = 0.82 which is greater than the alpha level 5%

P-value > α: The differences between the means are not statistically significant

If the p-value is greater than the significance level, you do not have enough evidence to reject the null hypothesis that the population means are all equal. Verify that your test has enough power to detect a difference that is practically significant.

A, B and C be sets. (a) Suppose that A ⊆ B and B ⊆ C. Does this mean that A ⊆ C? Prove your answer. Hint: to prove that A ⊆ C you must prove the implication, “for all x, if x ∈ A then x ∈ C.” (b) Suppose that A ∈ B and B ∈ C. Does this mean that A ∈ C? Give an example to prove that this does NOT always happen (and explain why...
