You construct a 95% confidence interval for a mean and find it to be 1.1 ± .8. Which of the following is true?
a.A test of the hypotheses H₀:μ=1.2,Ha:μ≠1.2 would reject H₀ at the 0.05 level
b.A test of the hypotheses H₀:μ=1.1,Ha:μ≠1.1 would reject H₀ at the 0.05 level
c.A test of the hypotheses H₀:μ=0,Ha:μ≠0 would reject H₀ at the 0.05 level
d.All three tests above would reject H₀ at the 0.05 level
e.A test of hypothesis cannot be performed fromonly a confidence interval.
