Suppose that you are trying to choose which of two IT projects to accept. Your company employs three primary selection criteria
for evaluating all IT projects: (1) proven technology, (2) ease of transition, and (3) projected cost savings.One option, Project Demeter, is evaluated as:Technology highEase of transition lowProjected cost savings highThe second option, Project Cairo, is evaluated as:Technology mediumEase of transition highProjected cost savings highConstruct a table identifying the projects, their evaluative criteria, and ratings. Based on your analysis, which project would you argue in favor of adopting? Why?

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.
