Since an instant replay system for tennis was introduced at a major tournament, men challenged 1400 referee calls, with the result that 413 of the calls were overturned. Women challenged 772referee calls, and 213 of the calls were overturned. Use a 0.01 significance level to test the claim that men and women have equal success in challenging calls. Complete parts (a) through (c)below.a.

Conduct an hypothesis testing using a 5% significance level Using P value or classical approach. Determine whether votes for governor in a particular election are independent of the voter's political party affiliation.
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.
