An oil brand claims that the average mileage with one gallon of their gasoline is 25mi. You recorded the mileage of 10 independent cars with a gallon of said gasoline and obtained an average of 23.7mi. You want to determine if this is enough evidence to say that the brand is overestimating. What is the alternative hypothesis for this problem? a. u < 25 b. C. u > 25 u = 23.7 d. u #25

A statistical program is recommended. The authors of an article found that the speed of a prey (twips/s) and the length of a prey (twips ✕ 100) are good predictors of the time (seconds) required to catch the prey. (A twip is a measure of distance used by programmers.) Data were collected in an experiment in which subjects were asked to "catch" an animal of prey moving across his or her computer screen by clicking on it with the mouse. The investigators varied the length of the prey and the speed with which the prey moved across the screen. The following data are consistent with summary values and a graph given in the article. Each value represents the average catch time over all subjects. The order of the various speed-length combinations was randomized for each subject.

In a chapter preview we presented a study showing that the handling money reduces our perception pain. in the experiment a group of college students was told that they were participating in a manual dexterity study. half of the students were given a stack of money to count and the other half got a stack of blank paper. after the counting task the participants were asked to dip their hands into balls of very hot water at 122 f, Andrade how uncomfortable it was. the following data show ratings of pain similar to the results obtained in the study.

An instructor for a test preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 14 students the first two times they took the test. Before taking the test for the second time, the students took the instructor's course to try to improve their critical reading test scores. At a = 0.01, is there enough evidence to support the instructor's claim? Complete parts (a) through (f).
