QUESTION 3 Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a left-tailed test is z = -1.83. O 0.0672; reject the null hypothesis O 0.0336; reject the null hypothesis 0.9664; fail to reject the null hypothesis O 0.0672; fail to reject the null hypothesis QUESTION 4 find the P-yalue. Also, use a 0.05 significance level and or fail to
Recently, a large academic medical center determined that 10 of 20 employees in a particular position were male, whereas 47% of the employees for this position in the general workforce were male. At the 0.05 level of significance, is there evidence that the proportion of males in this position at this medical center is different from what would be expected in the general workforce? What are the correct hypotheses to test to determine if the proportion is different? O A. Ho: T#0.47; H,: 1 = 0.47 O B. Ho: T20.47; H,: a 0.47 Calculate the test statistic. ZSTAT = (Type an integer or a decimal. Round to two decimal places as needed.) What is the p-value? The p-value is (Type an integer or a decimal. Round to three decimal places as needed.) State the conclusion of the test. the null hypothesis. There is V evidence to conclude that the proportion of males in this position at this medical center is different from the proportion in the general workforce.
QUESTION 4 An executive believes that no more than 80% of the company's employees take all of their vacation days. In a sample of 210 members, 158 employees took all of their vacation days. Therefore, the p-value is 0.0422. When testing the executive's (using a 5% level of significance), what can you conclude conceming the null hypothesis? O Reject the null hypothesis O Fail to reject the null hypothesis

Independent random samples of ?1 = 500 ??? ?2 = 500 and observations were selected from binomial populations 1 and 2, and ?1 = 120 and ?2 = 147 successes were observed.(a) What is the best point estimator for the difference (?1 − ?2) in the two binomialproportions?(b) Calculate the approximate standard error for the statistic used in part a.8. Refer to question 7. Find(a) a margin of error for the point estimate.(b) a 90% confidence interval for the difference (?1 − ?2) in the two binomialproportion
Under what circumstances is a t statistic used instead of a z-score for a hypothesis test? Justin wants to know whether a commonly prescribed drug does improve the attention span of students with attention deficit disorder (ADD). He knows that the mean attention span for students with ADD who are not taking the drug is 2.3 minutes long. His sample of 12 students taking the drug yielded a mean of 4.6 minutes. Justin can find no information regarding σx , so he calculated s2x =1.96. Determine the critical region using a one-tailed test with alpha = .05. Conduct the hypothesis test (Do the math and compare the t-critical and t-obtained values). State your conclusions in terms of H0 (Should you reject the H0 or fail to reject/accept the H0). Based on your analysis, is there a relationship between the drug and attention span?
Looking at youth depression scores from a general sample of random children in the US, we want to determine if our sample is significantly different than the national average of scores of children with depression in the US. The national average of scores on a measure of depression is 5 points. We have no reason to assume it will be higher or lower than the US national average. The sample: 11 9 12 3 3 4 13 1. What is the null and alternative hypotheses? Do not specify any directionality. 2. What did you discover (using 95% Cl)? Provide an interpretation.
It was claimed that 90% of all dentists recommend Tentodyne toothpaste. A consumer group doubted this claim and decided to test Ho: p = 0.9 against the alternate hypoth- esis H₁ : p < 0.9, where p is the proportion of dentists who recommend Tentodyne. A survey of 400 dentists found that 349 recommends this brand of toothpaste. What conclusion can be made at a level of significance of (a) a = 0.05 (b) a = 0.01? Suppose that instead of H₁, the alternative hypothesis was H₂ : p0.9. At 0.05 significance level, what would be the conclusion? Between the two (H₁ and H₂), which is the more appropriate alternative hypothesis in this case? Justify your answer.

Only 12% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 390 randomly selected registered voters surveyed, 62 of them will vote in the upcoming election. What can be concluded at the αα = 0.01 level of significance? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion The null and alternative hypotheses would be: H0:H0: ? p μ Select an answer > < ≠ = (please enter a decimal) H1:H1: ? p μ Select an answer ≠ < = > (Please enter a decimal) The test statistic ? z t = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? ≤ > αα Based on this, we should Select an answer accept reject fail to reject the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly higher than 12% at αα = 0.01, so…

Conduct a hypothesis test using the 5% significance level a) Construct hypotheses appropriate for the following question: Do these data provide evidence that the 8% value is inaccurate! OH P-0.08 H:p> 0.08 OH₂:p-0.08 Hap<0.08 Ho:p=0.08 HA:P 0.08 b) What proportion of children in this sample are nearsighted? Round your answer to 4 decimal places. c) Given that the standard error of the sample proportion is 0.0195 and the point estimate follows a nearly normal distribution, calculate the test statistic (use the 2-statistic). Round your answer to 2 decimal places. d) What is the p-value for this hypothesis test? Round your answer to 4 decimal places. P.- e) What is the decision for this hypothesis test?
