A law enforcement agent believes that at least 84% of the drivers stopped for speeding on Saturday nights are under the influence of alcohol. A sample of 84 drivers who were stopped for speeding on a Saturday night was taken. Seventy-five percent of the drivers in the sample were under the influence of alcohol. (a) State the null and alternative hypotheses. (Enter != for ≠ as needed.) H0: Ha: (b) Compute the test statistic. (c) Using the p-value approach, test the hypotheses at the 0.05 level of significance. Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. Do not reject H0. There is insufficient evidence to conclude that less than 84% of the drivers stopped for speeding on Saturday nights are under the influence of alcohol.Do not reject H0.

In a sample of 49 men, 38 said that they had less leisure time today than they had 10 years ago. In a sample of 49 women, 30 women said that they had less leisure time today than they had 10 years ago. At α=0.01, is there a difference in the proportions?Use p1 for the proportion of men with less leisure time. State the hypotheses and identify the claim with the correct hypothesis. H0 : p1=p2 ▼not claim H1 : p1≠p2 ▼claim This hypothesis test is a ▼two-tailed test. Find the critical value(s). Round the answer(s) to two decimal places. If there is more than one critical value, separate them with commas. Critical value(s):_______________
From the ANOVA results, test the hypothesis of equal means and show all five parts for the test. Use a=0.05 for the test Ho:? Ha:? F and PValue:? Reject Ho if:? Conclusion:?
The NAEP considers that a national average of 283 is an acceptable performance. Using α = .05, run a two-tail t-test for one sample to test Ho: µ=283 for the 2019 scores. Report the t-obt, df, and p-values. Would you reject the null hypothesis that the 2019 scores come from a population with average 283? If this is the case, does it come from a population from larger or smaller average?
The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65−74 years: n = 116, x = 12.5, and s = 6.35. Does this data indicate that average daily zinc intake in the population of all males age 65−74 falls below the recommended allowance? (Use ? = 0.05.)State the appropriate null and alternative hypotheses. H0: ? = 15Ha: ? ≠ 15H0: ? = 15Ha: ? > 15 H0: ? = 15Ha: ? ≤ 15H0: ? = 15Ha: ? < 15 Calculate the test statistic and determine the P-value.

which of the following statements is true if when using null hypothesis testing, our p value (in the sig column of spss output) is 0.069? -reject the null hypothesis -daily to reject the null hypothesis -reject the alternative hypothesis -fail to reject the alternative hypothesis
The average annual miles driven per vehicle in the United States is 11.1 thousand miles, with σ ≈ 600 miles. Suppose that a random sample of 36 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.9 thousand miles. Does this indicate that the average miles driven per vehicle in Chicago is different from (higher or lower than) the national average? Use a 0.05 level of significance. State the null and alternate hypotheses. a) H0: p = 11.1; H1: p > 11.1 b) H0: p = 11.1; H1: p < 11.1 c) H0: μ = 11.1; H1: μ > 11.1 d) H0: μ = 11.1; H1: μ ≠ 11.1 e) H0: p = 11.1; H1: p ≠ 11.1 f) H0: μ = 11.1; H1: μ < 11.1 (b) What sampling distribution will you use? What assumptions are you making? a) The standard normal, since we assume that x has a normal distribution with known σ. b) The Student's t, since we assume that x has a normal distribution with unknown σ. c) The Student's t, since we assume that x has a normal distribution with known σ.…
