Find an approximate 95% CI. a. H₀:= 50 x=53.4 standard error ofx= 4 (round your answers to 1 decimal place) The approximate 95% CI foris _ to _. The result of the hypothesis test is:

Reject H₀, because the null value is inside the 95% CI.

Reject H₀, because the null value is outside the 95% CI.

Fail to reject Ho because the null value is outside the 95% CI.

b.

H₀:= -2 x=-2.24 standard error ofx= 0.73 (round your answers to 2 decimal place) The approximate 95% CI foris _ to _. The result of the hypothesis test is:

Reject H₀, because the null value is inside the 95% CI.

Reject H₀, because the null value is outside the 95% CI. Fail to reject H₀, because the null value is inside the 95% CI.

c.

H₀:₁-₂= 0 x₁= 81008,x₂= 93264 standard error ofx₁-x₂= 1642 The approximate 95% CI for₁-₂is _ to _. The result of the hypothesis test is:

Reject H₀, because the null value is inside the 95% CI.

Reject H₀, because the null value is outside the 95% CI. Fail to reject H₀, because the null value is inside the 95% CI.

Fail to reject H0, because the null value is outside the %95 CI.
