Several years ago, a government agency reported the default rate (the proportion of borrowers who default on their loans) on a certain type of loan at 0.025. Set up the null and alternative hypotheses to determine if the default rate this year is greater than 0.025. What are the correct null and alternative hypotheses to test the claim that the default rate is greater this year?

A psychologist specializing in marriage counseling claims that, among all married couples, the proportion p for whom her communication program can prevent divorce is at least 79%. In a random sample of 250 married couples who completed her program, 192 of them stayed together. Based on this sample, can we reject the psychologist's claim at the 0.05 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table.

Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.7 bpm. For a random sample of 169 adult males, the mean pulse rate is 68.9 bpm and the standard deviation is 11.5 bpm. A. Express the original claim in symbolic form. B. Identify the null and alternative hypotheses.
Previously, forcing a mother smoked more than 21 cigarettes during the pregnancy. A doctor believes that the pregnancy of mothers who smoke 21 cigarettes or more is less than 4% today. She randomly selects 140 pregnant mothers and find that 2 of them smoke 21 or more cigarettes during pregnancy. Test the research statement at the = 0.05 level of significance. identify the correct Null and alternative hypothesis. use technology to find the P value. P value =_. (round to three decimal places as needed.) should one reject the null hypothesis? or should one not reject the null hypothesis?
A statistician wishing to test a hypothesis that students score at most 75% on the final exam in an introductory statistics course decides to randomly select 20 students in the class and have them take the exam early. The average score of the 20 students on the exam is 72% and the standard deviation in the population is known to be = 15%. The statistician calculates the test statistic to be –0.8944. If the statistician chose to do a two-sided alternative, the P-value would be calculated by: a. finding the area to the right of –0.8944 and doubling it. b. finding the area to the left of –0.8944 and doubling it. c. finding the area to the right of the absolute value of –0.8944 and dividing it by two. d. finding the area to the left of –0.8944
The director of research and development is testing a new medicine. She wants to know if there is evidence at the 0.05 level that the medicine relieves pain in more than 388 seconds. For a sample of 67 patients, the meantime in which the medicine relieved pain was 390 seconds. Assume the standard deviation is known to be 17. Step 1 of 5 : Enter the hypotheses:
