Question

For each question, create an approximate 95% CI and then decide whether the null hypothesis should be rejected.

a.
H₀: μ = 50
x=53.7
standard error of x = 1.6
(round your answers to 1 decimal place)

The approximate 95% CI for μ is _____ to _____
The result of the hypothesis test is:

b.
H₀: μ = -2
x=-2.44
standard error of x = 0.51
(round your answers to 2 decimal place)

The approximate 95% CI for μ is ____ to ____
The result of the hypothesis test is:

c.
H₀: μ₁ - μ₂ = 0
x₁ = 82734, x₂ = 92216
standard error of x₁ - x₂ = 1193

The approximate 95% CI for μ₁ - μ₂ is ____ to _____
The result of the hypothesis test is:
