1-A psychology professor of a very large class wanted to know whether students who turned in their tests first had different scores than the overall mean on the test. The overall mean score on the test was 85 with a standard deviation of 14; the scores were approximately normally distributed. The mean score for the first 25 tests was 80. Which of the following is true? A) The research hypothesis is that people that turn in their tests first will not score differently from the overall mean on the test B) The research hypothesis is that people that turn in their tests first will score lower than the overall mean on the test C) The research hypothesis is that people that turn in their tests first will score higher than the overall mean on the test D) The null hypothesis is that people that turn in their tests first will not score differently than the overall mean on the test 2- A social psychologist interested in relationships has developed a scale that measures the degree of affection adult men feel for their father. She found that the general population distribution is skewed to the right, the mean degree of affection is 70, and the standard deviation is 10. She is now wondering if men who grew up with divorced parents will score lower on the scale than men who grew up in a home with both parents. She samples a group of 100 men from divorced families and finds that their mean is 59. What is the shape of the comparison distribution? A) It cannot be determined from the information given B) Skewed to the left C) Very close to a normal distribution D) Skewed to the right
