A recent study at a university showed that the proportion of students who commute more than 15 miles to school is 25%. Suppose we have goodreason to suspect that the proportion is greater than 25%, and we carry out a hypothesis test. State the null hypothesis H, and the alternativehypothesis H, that we would use for this test.Ho: 0H;: DO

The FDA regulates that fish that is consumed is allowed to contain 1 mg/kg of mercury. In Alaska, bass fish were collected in 36 different lakes to measure the amount of mercury in the fish. Do the data provide enough evidence to show that the fish in Alaska lakes has more mercury than the allowable amount? Below, set up the Null Hypothesis Ho and the Alternative Hypothesis HA. Ho: H (? HẠ: H (?

2. Suppose a 95% CI for the proportion of adults that regularly attend a tae kwon do class at least once a week was found to be (0.2534, 0.3894). decision a. For the null and alternative hypothesis: Ho: p = 0.40 versus Ha: p # 0.40, what is for this test of hypothesis? your b. Based on the CI, which of the following statements gives the best conclusion about the true value of the proportion of adults that regularly attend a tae kwon do class at least once a week? i. I am 95% confident that the proportion of adults that regularly attend a tae kwon do class at least once a week is greater than 40%. ii.

-Find the correct null hypothesis and for each correct alternative hypothesis 3. Suppose you hear a claim that the average score on a national exam is 78. You think the average is higher than that. Set up your null and alternative hypotheses.
14% of all Americans suffer from sleep apnea. A researcher suspects that a lower percentage of those who live in the inner city have sleep apnea. Of the 341 people from the inner city surveyed, 34 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.01? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v Select an answer V (please enter a decimal) H1: ? v Select an answer V (Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly smaller than 14% at a = 0.01, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is equal to…
A study by researchers at a university addressed the question of whether the mean body temperature of an animal is 98.8°F. Among other data, the researchers obtained the body temperatures of 104 healthy animals. Suppose you want to use those data to decide whether the mean body temperature of healthy animals is less than 98.8°F. Complete parts (a) through (c) below. -.... a. Determine the null hypothesis. Ho: H (Type an integer or a decimal. Do not round.) b. Determine the alternative hypothesis. Ha: H (Type an integer or a decimal. Do not round.) c. Classify the hypothesis test as two tailed, left tailed, or right tailed. The hypothesis test is
A college professor states that this year's entering students appear to be smarter than entering students from previous years. The college's records indicate that the mean IQ for entering students from earlier years is 110.4. Suppose that we want to sample a small number of this year's entering students and carry out a hypothesis test to see if the professor's statement can be supported. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0= H1=

The table to the right includes results from polygraph experiments. In each case, it was known if the subject lied or not, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truths and lies? State the null and the alternative hypotheses. Choose the correct answer below. O A. Ho: The row and column variables are independent. H₂: The row and column variables are dependent. OB. Ho: At least one of the values is different from the others. Ha: All values in the table are equal. OC. Ho: All values in the table are equal. Ha: At least one of the values is different from the others. Polygraph indicated that subject lied Polygraph indicated that subject did not lie O D. Ho: The row and column variables are dependent. H₂: The row and column variables are independent. Did the subject…
