Questions 1 and 2: Set up the Null and Alternative hypotheses to test the following claims: 1. A health insurance company wants to determine if less than 25% of U.S. residents have been to a hospital emergency room within the past year. State the null and alternative hypotheses. H0: HA: 2. A company makes canned clam chowder (a delicious New England tradition). On the label, the company claims that the chowder contains (on average) 3.5 grams of Total Fat per serving. A consumer group would like to test this claim is true. State the null and alternative hypotheses that you would use to test if the mean amount of Total Fat per serving differs from 3.5 grams: H0: HA:

An experiment was conducted to test whether classical music helps with mathematical performance. To study this, participants (n=9) were given an algebra test. Half of the sample completed the test in a room with classical music playing while the other half completed it in a room with no sounds at all. After a brief rest, the two groups switched rooms and completed a slightly modified version of the algebra test. Thus, all participants experienced both conditions. The scores for the two conditions were then compared, showing that listening to classical music did help mathematical performance by an average of MD =2 points with SS =32. a. Calculate the estimated standard error. b. Compute the t statistic and state the conclusion of these findings.

facing up. The student rolls the cube 100 times and lands with 6 facing up 20 times. The P-value for the test of the hypotheses, Hop-0.17 and H p>0.17, is 0.19. What is the correct conclusion given a=0.05? O Because the P-value is less than a=0.05, the student should reject Ho. O Because the P-value is less than a=0.05, the student should reject Ho. O Because the P-value is greater than a=0.05, the student should reject Ho: O Because the P-value is greater than a=0.05, the student should fail to reject Ho.

Four salesmen play "odd man out" to see who pays for lunch. They each flip a coin, and if there is a salesman whose coin doesn't match the others he pays for lunch. To clarify, the "odd man" must get heads while the other three get tails OR he must get tails while the other three get heads. Of course, since it is possible for two men get heads and two men get tails, not all flips will result in finding an "odd man". If this occurs the salesmen would be forced to flip again. What is the probability that there is an "odd man" the first time they flip?
