In a rural area only about 33% of the wells that are drilled find adequate water at a depth of 100 feet or less. A local man claims to be able to find water by dowsing, that is, using a forked stick to indicate where the well should be drilled. You check with 66 of his customers and find that 27 have wells less than 100 feet deep. Answer the questions below. Assume the independence assumption is met. (a) Write appropriate hypotheses. Họ: The percentage of successful wells drilled by the dowser is equal to 33%. HA: The percentage of successful wells drilled by the dowser is greater than 33%. (b) Check the necessary assumptions. The independence assumption is satisfied. The randomization condition is not satisfied. The 10% condition is satisfied. The success/failure condition is satisfied. (c) Perform the mechanics of the test. What is the P-value? P-value = (Round three decimal places as needed.)

Solve the following problems. Use the steps in conducting hypothesis tests.We are interested in whether the proportions of female suicide victims for ages 15 to 24 are the same for the whites and the blacks races in the United States. We randomly pick one year, 1992, to compare the races. The number of suicides estimated in the United States in 1992 for white females is 4,930. Five hundred eighty were aged 15 to 24. The estimate for black females is 330. Forty were aged 15 to 24. We will let female suicide victims be our population.
The national average SAT score is roughly 1500. We would like to see if the high school seniors who apply to Duke have higher than average SAT scores. We randomly sample 100 applicants' files and record their SAT scores. Which of the following is the correct set of hypotheses for this research question? Hint: think about how many samples we have data from. OHO: H= 1500; HA: µ = 1500 Ho: H Duke National; HA: H Duke National Ho: x= 1500; HA: x > 1500 OHO: H = 1500; HA: > 1500 O Ho: P = 1500; HA: P > 1500

Find the P-value for the indicated hypothesis test. Round all proportions and standard scores to two decimal places.In a sample of 47 adults selected randomly from one town, it is found that 10 of them have been exposed to a particular strain of the flu. Find the P-value for a test of the claim that the proportion of all adults in the town that have been exposed to this strain of the flu is 8%.

Wait times for 11 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal. 12, 13, 13, 15, 13, 11, 14, 13, 15, 11, 15 What can be concluded at the the a = 0.01 level of significance level of significance?
You may need to use the appropriate technology to answer this question. Test the following hypotheses by using the x? goodness of fit test. Ho: PA = 0.40, PR = 0.40, and p. = 0.20 H: The population proportions are not pa = 0.40, PR = 0.40, and P. = 0.20. A sample of size 200 yielded 20 in category A, 60 in category B, and 120 in category C. Use a = 0.01 and test to see whether the proportions are as stated in Ho: (a) Use the p-value approach. Find the value of the test statistic. 35 Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. O Do not reject H,. We cannot conclude that the proportions differ from 0.40, 0.40, and 0.20. O Reject H,. We conclude that the proportions are equal to 0.40, 0.40, and 0.20. O Reject H. We conclude that the proportions differ from 0.40, 0.40, and 0.20. O Do not reject H. We cannot conclude that the proportions are equal to 0.40, 0.40, and 0.20.

A December 2017 Gallup Poll reported that 43% of Americans use the internet for an hour or more each day. You suspect that a greater proportion of students at your school use the internet that much. You take a random sample of 60 students and find that 36 of them use the internet for an hour or more each day. Assume your school has more than 600 students. You will test the hypotheses H, : p = 0.43, H,:p>0.43 , where p= the true proportion of students at your school who use the internet for an hour or more each day. Which of the following gives the correct test statistic for this test? 0.43 - 0.6 Z = (0.6)(0.4) 60 0.43-0.6 (0.6)(0.4) 600 0.6-0.43 (0.6)(0.4) 60 0.6 - 0.43 (0.43)(0.57) 60 36 - 60 (36)(24) 60
