Use the confidence level and sample data to find a confidence interval for estimating the population μ. Round your
answer to the same number of decimal places as the sample mean.
Test scores: n = 104, x = 95.3, σ = 6.5; 99% confidence

Suppose you collect a sample that has a mean of 37 with a 99% confidence interval of [32,42], and you are interested in the hypothesis test below at the α=0.05 level.
| H0: μ=43 |
| Ha: μ≠43 |
a) You should ask for more information because the sample size and standard deviation are needed for a hypothesis test of this kind.
b) You should fail to reject the null hypothesis because the p-value is greater than 0.05.
c) You should ask for more information because the confidence interval does not match the αα level.
d) You should reject the null hypothesis because the p-value is less than 0.05.
