IBM is interested in comparing the average project completion time using last year's software versus using the new software. So, selected 36 projects using last year's software and 36 projects using the new software. The completion time (in hours) for each pm entered into Excel. Can IBM conclude the average project completion time using the new software is greater than the average prc year's software at a=.025? Based on this paragraph of text, use the correct excel output above to answer the following question. What would the P-value be for Ha: PLast Year - PNew <0? a. .995 < P-value <.9975 b. .9975 < P-value <.999 c. None of the answers is correct d. .0025 < P-value <.005 001 < P-value <.0025

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
