Automobile accident and asked what they saw. One group of students was asked how fast were they going when they smashed into the car? Other group verb was changed to hit. Smashed into reported higher rates of speed than hit. Suppose a researcher repeats this study with current college students and obtains the following results. Smashed into Hit n=15 n=15 M=40.8 M=34.0 SS=510 SS=414 1. State the hypothesis 2. Do the results indicate a significantly higher estimated speed for the smashed into group? Use a two-tailed test with a=.05. Compute estimated Cohen's D to measure size of the effect. State numerical value and meaning.

The commercial for the new Meat Man Barbecue claims that it takes 14 minutes for assembly. A consumer advocate thinks that the assembly time is lower than 14 minutes. The advocate surveyed 12 randomly selected people who purchased the Meat Man Barbecue and found that their average time was 13.5 minutes. The standard deviation for this survey group was 2.1 minutes. What can be concluded at the the a = 0.01 level of significance level of significance? You may assume the data are normally distributed.
Suppose that BC financial aid allots a textbook stipend by claiming that the average textbook at BC bookstore costs $$ 62.87. You want to test this claim. The null and alternative hypothesis in symbols would be: H0:μ=62.87H1:μ≠62.87 The null hypothesis in words would be: The average price of all textbooks from the store is $$ 62.87 Based on a sample of 120 textbooks at the store, you find an average of 71.47 and a standard deviation of 14.2. The point estimate is: _____________(to 3 decimals). The 90 % confidence interval (use z*) is:__________ to __________ (to 3 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis
