Hi there, I just need help with the last couple sub parts of this question. I'm having a difficult time understanding this. Can somebody help me please? Below is the data for a personality questionnaire measuring conscientiousness. These data were taken from a random sample of 16 undergraduate psychology majors. In the general population, scores on this questionnaire are normally distributed with a mean (μ) of 50. You hypothesize that this sample is not representative of the general population. Specifically,...

It may be that sunshine has a unique effect on learning statistics. Previous research has been in disagreement, with some studies showing that sunshine increases amount learned whereas others show sunshine has detrimental effects on learning. You would like to determine for yourself whether or not sunshine makes a DIFFERENCE on statistics learning. Let's assume you take five statistics students and give them a lesson on a sunny day, and then take the same students and give them the related...
Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis H_0: mu_D = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. Complete the following table by calculating the differences and the...
