For each of the following scenarios state whether h0 should be rejected or not. state any assumptions that you make beyond the information that is given.
(a) h0 : µ = 4, h1 : µ 6= 4, n = 15, x = 3.4, s = 1.5, α = .05.
(b) h0 : µ = 21, h1 : µ < 21, n = 75, x = 20.12, s = 2.1, α = .10.
(c) h0 : µ = 10, h1 : µ 6= 10, n = 36, p-value = 0.061.

a) , n = 15 , X=3.4 , S=1.5 , α = .05

Formula :

p- value = 0.607(using calculator)

α = .05

p- value > α

So, we failed to reject null hypothesis

b) , n =75 , X=20.12 , S=2.1 , α = .10

Formula :

p- value = 0.000412(using calculator)

α = .1

p- value< α

So, we reject null hypothesis

(c) , n = 36, p-value = 0.061.

Assume α = .05

p-value = 0.061.

p- value > α

So, we failed to reject null hypothesis
