Since an instant replay system for tennis was introduced at a major tournament, men challenged 1412 referee calls, with the result that 411 of the calls were overturned. Women challenged 764 referee calls, and 227 of the calls were overtumed. 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) belon Consider the first sample to be the sample of male tennis players who challenged referee calls and the second sample to be the sample of female tennis players who challenged referee calls.

The venomous eastern cottonmouth is a water snake. It is also viviparous, meaning it gives birth to live babies, not eggs like many reptiles. Here is a random sample of litter sizes from the eastern cottonmouth.5 12 7 3 6 8 12 3 7 4 9 6 12 7 5 6 10 3 10 8 6 12 5 6 10 63 8 4 5 7 6 11 7 6 8 10 14 8 7 11 5 4 Using a TI 84 graphing calculator:  Construct an 85% confidence interval for the population meanlitter size, µ.

The Tokyo Marine Consultant wants to conduct a survey with the aim is to estimate banking and hospital service time. For this reason, observations are made on the waiting time data of each customer for one period which is obtained from the two business sectors. The sample data was taken randomly from 11 customers separately and independently from bank and hospital customers. The following data are the waiting times from 22 samples ofcustomers.                                          Waiting Time (In minutes) Banking   9.66  5.9     8.02     5.79   8.73   3.82   8.01   8.35   10.1   6.6    5.6Hospital   4.21  5.55   3.02     5.13   4.77   2.34   3.54   3.2      4.5    6.1    0.3 a. Calculate the average and standard deviation of waiting time at banks and hospitals. b. Assuming the population variance is the same, determine the estimated limits of the difference between the average waiting time from the survey results from the survey with a significance level of 5%?c.

Based on the results, does it appear that men and women may have equal success in challenging calls?

Among drivers who have had a car crash in the last year, 110 were randomly selected and categorized by age, with the results listed in the table below. Age Under 25 25-44 45-64 Over 64 Drivers 44 24 15 27 If all ages have the same crash rate, we would expect (because of the age distribution of licensed drivers) the given categories to have 16%, 44%, 27%, 13% of the subjects, respectively. At the 0.05 significance level, test the claim that the distribution of crashes conforms to the distribution of ages. The test statistic is x²= The critical value is x² = The conclusion is OA. There is sufficient evidence to warrant the rejection of the claim that the distribution of crashes conforms to the distibuion of ages. OB. There is not sufficient evidence to warrant the rejection of the claim that the distribution of crashes conforms to the distibuion of ages.

Suppose that in a random selection of 100100 colored​ candies, 2323​% of them are blue. The candy company claims that the percentage of blue candies is equal to 2525​%. Use a 0.100.10 significance level to test that claim.
