The statement that gives the best conclusion that should be made based on the results and provides the best explanation for the conclusion is option D;
D. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the cover designs were randomly assigned to stores
Step-by-step explanation:
The data given in the question are presented as follows;
The particulars the CD manufacturer wants to determine = The CD cover design that will generate more sales
The mode of selection of the stores for the test = Random selection
The number of stores in each group of stores, n = 35 stores
The number of sets of stores tested = 2 sets of stores
Let represent the mean number CDs sold at one set of stores and
represent the mean number CDs sold at the other set of stores
The null hypothesis, H₀; =
The alternative hypothesis, H₀; ≠
Given that the statistical analysis shows that the difference in mean between the two sets of randomly selected stores is significant, we therefore should reject the null hypothesis and accept the alternative hypothesis that there is a significant difference in CD sale attributable to the difference in cover design as the CDs having on of two cover design where assigned randomly to the stores.
Answer:
Step-by-step explanation:
I'm just going to go out on a limb here and assume that those are a set of poorly made parenthesis. This, then, would be your equation:
The first thing to do is distribute through the parenthesis to get:
Next is to get rid of the denominators by multiplying by the LCM of 77:
which gives you:
77x + 11x + 7x + x = 4620 and
96x = 4620 so
