Rumor has it going to class and reading a text book will improve your chances of doing well in your stats class. You notice that there are 4 students that always go to class and review the text book everyday. To determine if rumours are true, you ask those 4 students their marks on the quiz and find out thier marks are: 60,60,61,67. Based on these scores and the knowledge that the exam scores are normally distributed (hypothesized pop mean is 50 and standard deviation of 10)what can you conclude about going to class and reviewing the text book everyday? do you reject or fail to reject the null hypothesis? What is the effect size? assuming a=0.05, state your hypothesis for a one tailed test, the critical test statistic, your conclusion?
