Suppose that in the hypothesis test with null hypothesis Ho: μ = 14.0 at a= 0.05, that the value of 13.0 for sample mean results in null hypothesis not being rejected. That corresponds to confidence interval result of
A) The 95% confidence interval for mean contains the value 14.0B) The 95% confidence interval for mean does not contain the value 14.0C) There is insufficient information as to if 95% confidence interval for mean does or does ot contain value13.0D) 0.05% confidence interval for mean contains the value 13.0.
