10e solve thisQIn a random sample of males, it was found that 22 write with their left hands and 220 do not. In a random sample of females, it was found that 70 write with their left hands and 452 donot. Use a 0.01 significance level to test the claim that the rate of left-handedness among males is less than that among females. Complete parts (a) through (c) below.Za.

The coach of a very popular men’s basketball team claims that the average distance the fans travel to the campus to watch a game is 35 miles. The team members feel otherwise. A sample of 16 fans who travel to games was randomly selected and yielded a mean of M= 36 miles and s= 5 miles. Test the coach’s claim at the 5% (.05) level of significance. one-tailed or two-tailed test: State the hypotheses: df= tα or t value for the critical region = sM = t (test statistic)= Decision:
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.

2. Ashley wishes to see if her ballroom dance classes, or her swing dance classes are more popular. Sampling 27 ballroom classes gives an average of 34.3 people in attendance with a standard deviation of 4.5 people, while a random sample of 27 swing classes gives an average of 30.7 people with a standard deviation of 2.3 people. Assume the two classes are independent. For each of the questions below, use a significance level of 0.01. a) Determine whether the population variances of the two classes are different. b) Based on your answer to part a), use the appropriate hypothesis test to determine if the mean class attendance differs between the two classes. c) Repeat part b with the other situation (in other words, assume the opposite of your conclusion for part a is true).How does your answer change based on what you know about the variance?
