Q2 part 2
I need a hypothesis, description and interpretation, please! Thank you!!
Dr. V. noticed that the more frequently a student is late or absent from class the worse he or she performs on the final exam. He decided to investigate. Dr. V. collected a random sample of 22 students. This sample includes the number of times a student is absent and their grades on the final exam. Discuss the implications of the calculated Statistical Power and the probability of a Type II Error. Significance Level: Use a 5% significance level. What is/are the Critical Value(s)? Calculate the coefficient of determination, r2, using Excel’s RSQ function. Explain what it means.
Use a 0.05 significance level to test the claim that the different samples come from populations with the same mean. Use the traditional method the null and alternative hypothesis, the critical value, the test statistic, Draw the graph and label the test statistic, critical value and rejection regions.

The student population at the state college is made up of 60% females and 40% males. The college theater department recently staged a production of a modern musical. A researcher recorded the gender of each student entering the theater and found a total of 37 females and 18 males. Is the gender distribution for theater goers significantly different from the distribution for the general college? Test at the .05 level of significance.
