Question

A	5.8 //6.8 //8.7 //5.7 //5.8
B	8.2 //7.1 //7.0// 6.9// 8.3

Data sets A and B are dependent. Find the critical value, t ₀, to test the claim that μ _d = 0. Use x=0.01

Answer 1

Using Excel

data -> data analysis -> t-Test: Paired Two Sample for Means

p-value = 0.2919 > alpha (0.01)

hence we fail to reject the null hypothesis

we conclude that there is not significant difference

Please give me a thumbs-up if this helps you out. Thank you! :)
