Project #17382 - Statistics 2

1. Assume the following information for equal-sized samples and make the appropriate t tests

a. Group 1: x¯ = 25, s² = 27.8, n = 15; Group 2: x¯ = 23, s² = 27.8, n = 15

 

b. Group 1: x¯ = 25, s² = 27.8, n = 15; Group 2: x¯ = 29, s² = 27.8, n =15

 

*Please note the (-) symbol is supposed to be directly above the (x). I didn’t know how to create that symbol.

 

 

2.Determine the probability of the t test result in (a) and (b) of the above exercise and decide whether you would accept or reject the hypothesis of no difference between the two groups in each case

 

Please use an excel spreadsheet to complete. Thanks!
