Students believe that Professor A has a lower class mean exam score than Professor B. To test this claim, 40 randomly chosen exams were selected from professor A and 26 exams were randomly selected from Professor B. Professor A had a sample mean of 80 with a sample standard deviation of 10. Professor B had a sample mean of 86 with a standard deviation of 14. Assume the exam scores are normally distributed for both professors. Use the PHANTOMS steps...

Suppose that the average grade on our midterm exam (in our class of size 116 students) was 75. Which is more likely to be closer to 75: a) the exam grade of a randomly selected student in the class? b) the mean exam grade of a randomly selected sample of 10 students in the class? Explain your reasoning.

A police officer exam have an average score of 79 with a standard deviation of 4.5. Assume police officer exam scores follow a normal distribution.

3. You hear a claim that the average score on a national exam is higher than it used to be, which is 77. Of course you response is "Oh it is, huh? We'll see about that!" You test this claim by getting a random sample of 60 exam scores for this national exam. The sample mean is 80 and the sample standard deviation is 8.2. Be sure to check if the conditions are met, and show how you checked them...

1) One assumption for using hypothesis testing for Pearson correlation is that one variable should vary equally at each level of the other variable. What is the easiest way to determine if this assumption has been met?              Calculate the cross-products of the deviation scores; if the result is positive, then the assumption has been met. If the calculation of r is high, then the assumption has been met. Conduct a post-hoc test following the calculation of r. Draw a...

A principal claims the students in his school have above-average test scores for a particular standardized test. A sample of 50 students from his school were found to have an average test score of 77.2. The population mean for test scores for this particular test is 75, with a standard deviation of 9 (so we can assume that the population test score is normally distributed). Set up a hypothesis test to determine whether this principal’s claim is correct (use alpha...
