Assuming $H_0$ is true, what is the distribution of the test statistic? t(29)
Assuming $H_0$ is true, what is the expected value of the test statistic? 87.70
The sample mean of 87.7 was ___ standard errors below the mean of 90. 1.615
Can someone verify that my work is correct? In particular, I'm not entirely sure about the second question. Will the test statistic actually be 0 in this case (as it wouldn't deviate from the mean)?
