So, a consultant for IBM randomlyselected 36 projects using last year's software and 36 projects using the new software. The completion time (in hours) for each project was recorded and thenentered into Excel. Can IBM conclude the average project completion time using the new software is greater than the average project completion time using lastyear's software at a=.005? Based on this paragraph of text, use the correct excel output above to answer the following question.For the hypothesis stated above, what is the decision (in terms of "New" minus "Last Year")?O a. Fail to reject Ho because p-value > a.b.Reject Ho because p-value > a.OC. Fail to reject Ho because p-value < a.Od. None of the answers is correctOe. Reject Hn because p-value < a.Click Save and Submit to save and submit. Click Save All Answers to save all answers.MacBook Pro

dentify the null hypothesis (, alternative hypothesis , test statistic, critical value(s), P-value (range of P-value), conclusion about the null hypothesis, and final conclusion that addresses the original claim. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use a 0.05 significance level to test the claim that the mean IQ score of people with low lead levels is greater than the mean IQ score of people with high lead levels. 2. Construct a confidence interval suitable for the testing the given claim. Low Lead Level High Lead Level n 1 = 78 n 2 = 21 X1=92.88 X2=86.90 s 1 = 15.34 S2=8.99
