A statistics instructor gave a four-question true-false quiz to his class of 150 students. The results were asfollows.Number correct 01 2 3 4Observed2 13 29 71 35The instructor thinks that the students may have answered the questions by guessing so that the probabilitythat any given answer is correct is 0.5. Under this null hypothesis, the number of correct answers has abinomial distribution with 4 trials and success probability 0.5. Perform a chi-square test of this hypothesis.Can you reject Ho at the a= 0.05 level?

Baldur is very interested in statistics and spinning and he decided to combine these two interests and carry out the following research. He randomly selected 100 Reykjavik residents and asked them two questions. On the one hand whether they want chocolate, ice cream or caramel on their pacifier and on the other hand what gender they are. Questions 4-6 deal with Baldur's survey. Baldur's question: "What do you want most on your spinner?" Has three possible answers:1) chocolate, 2) ice cream, 3) caramel, What type is the variable that Baldur records? 1. Continuous category variables. 2. Continuous number variables. 3. Unordered category variables. 4. Sorted category variables. Baldur is interested in investigating whether there is a connection between the two variables, gender and what people want on their spinner. What kind of hypothesis test should Baldur use? 1. Ki-square test. 2. Hypothesis test for two averages. 3. Variance analysis. 4. Simple linear regression. Assume that the…

To compare two elementary schools regarding teaching of reading skills, 12 sets of identical twins were used. In each case, one child was selected at random and sent to school A, and his or her twin was sent to school B. Near the end of fifth grade, an achievement test was given to each child. The results follow: Twin Pair 1 2 3 4 5 6 School A 80 145 118 90 112 118 School B 83 135 115 105 105 113 Twin Pair 7 8 9 10 11 12 School A 98 112 115 144 124 96 School B 93 87 98 132 135 105 Suppose a sign test for matched pairs with a 1% level of significance is used to test the hypothesis that the schools have the same effectiveness in teaching reading skills against the alternate hypothesis that the schools have different levels of effectiveness in teaching reading skills. Let p denote portion of positive signs when the scores of school B are subtracted from the corresponding scores of school A.…
