The paragraph below is the study questions 16-21 d The Board of Transportation and Safety (BTS) wants to examine the safety mechanisms of A, B, and C-class cars. Samples of 7 cars for each of the classes were used. The board members collect the pressure exerted overall on the driver's body during a crash impact test. The BTS wants to see if there if a difference among the 3 classes of cars. Assume alpha of 0.05. What type of statistical test would be appropriate? O Pearson correlation O Multiple linear regression O one-way independent ANOVA O two-way independent ANOVA O simple linear regression QUESTION 17 Which of the following is the correct alternative hypothesis?

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 pieces of paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122°F) and rate how uncomfortable it was. The following data show ratings of pain similar to the results obtained in the study. A. State null and alternative hypotheses b. Report results of statistical test, i.e., significant or not?

How many hours of sleep do people get by listening to music? I record 10 subjects’ hours of sleep after they listen to 4 types of music: White noise, Rock, Pop, and Classical. For each music condition, they provide an average amount of hours of sleep they got for 1 week. Using the following data, test whether there is a significant difference in hours of sleep between types of music at an alpha of 0.01.
