Suppose we are interested investigating the mean \muμ for some population. We want to test the hypotheses H0:μ=5.5 Ha:μ=5.5 a)What type of test would be appropriate here and why? b)We take a sample of size n = 25, and find a sample mean of 6.3, with an sd of 1.8.Which of the following choices do we still need to know in order to apply the test from the previous part? Choice 1:We have a random sample. Choice 2:The distribution of the quantitative variable is approximately normal in the population. Choice 3:The distribution of the quantitative variable is approximately normal in our sample. Choice 4:Our sample size is at least 30. c)Find the test statistic for our hypothesis test. d)The P-value is______ e)At the α=0.05 significance level, what conclusions can we make and why? Choice 1:Reject the null hypothesis. Choice 2:Fail to reject the null hypothesis.

for d how can you calculate the p value without excel? need to be able to do on a test without excel or statkey. It is also saying the answer is incorrect. P does not equal 0.036
