The answer is Boxplot II. The standard deviation for the data associated with Boxplot II will likely have a larger standard deviation. Boxplot II has a greater spread than Boxplot I, as measured by the interquartile range, which is related directly to the standard deviation of a data set.
Answer:
0.95 and 1.06
Explanation:
The computation of the present value index is shown below:
Present value index = Present Value of net cash Flow ÷ Amount invested
So for each projects, it would be
Particulars Des Moines Cedar Rapids
Total present value of
net cash flow (A) $712,500 $848,000
Amount invested (B) $750,000 $800,000
Present value index (A ÷ B) 0.95 1.06
Answer : The p-value of 0.0743 is greater than alpha at 0.05; so we fail to reject the null hypothesis and conclude that there is no significant difference in the number of unique users before and after a change in policy.
In this question, the manager wants to know if the number of users has changed.
So, the null and alternate hypotheses are:
Null Hypothesis: 
Alternate Hypothesis :
Type of test : Two-tailed test
The level of significance is 95%
We can calculate alpha (α) as follows:


The p value = 0.0743.
We use the following rules to arrive at a conclusion when p-values and alpha is given:
If
, reject the null hypothesis
If
, we don't reject the null hypothesis.
Since the p-value is greater than alpha, we don't reject the null hypothesis.
