Abigail, who works for a region's department of health, is looking for evidence that the percentage of adults in the region who are current smokers has decreased from 15.8% in 2015, She gathers a random sample of adults in the region and asks each individual if he or she currently smokes. Abigail found that 40 of the 277 adults who were surveyed are current smokers. What are the null and alternative hypotheses for this hypothesis test? Select the correct answer below: O Ho: p0.158 Ha : p=0.158 0 Ho : p= 0.158 Ha: p> 0.158 Ho : p: 0.158 Ha p0.158 10 ĺHo:p=0.158 Ha: p0.158

A medical researcher claims that the proportion of people taking a certain medication that develop serious side effects is 12%. To test this claim, a random sample of 900 people taking the medication is taken and it is determined that 93 people have experienced serious side effects.. The following is the setup for this hypothesis test: Ho :p 0.12 Ha p 0.12 In this example, the p-value was determined to be 0.124. come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%) Select the correct answer below: The decision is to reject the Null Hypothesis. The conclusion is that there is enough evidence to reject the claim O The decision is to fail to reject the Null Hypothesis. The conclusion is that there is not enough evidence to reject the claim

Suppose P(A) = P(B) = 0.25 and P(AUB) = 0.45. What is P(AN B)?

A researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are H0:p = 0.4 and Ha: p < 0.4. The test statistic and p-value for the test are z = -3.01 and p-value = 0.0013. For asignificance level of a= 0.05, choose the correct conclusion regarding the null hypothesis.H0:________________________ Ha:_______________________Compare the p-value and a:_______________Decision:_________________________Conclusion:___________________________________________________________

An education researcher claims that 57% of college students work year-round. In a random sample of 600 college students, 342 say they work year-round. At a = 0.05, is there enough evidence to reject the researcher's claim? Complete parts (a) through (e) below. (a) Identify the claim and state Ho and H3. Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) OA. % of college students work year-round. O B. At most % of college students work year-round. O C. The percentage of college students who work year-round is not O D. At least % of college students work year-round. Let p be the population proportion of successes, where a success is a college student who works year-round. State H, and Ha. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) O A. Ho: p> O B. Ho: ps O C. Ho: p= Ha: ps Hại p> H3:p = O D.…

A null and alternative hypothesis are given. Determine whether the hypothesis test is​ left-tailed, right-tailed, or​ two-tailed.   H0​: p ≥ 0.2 Ha​: p < 0.2 What type of test is being conducted in this​ problem?

A physician wants to determine if a supplement is effective in helping men lose weight. She takes a random sample of overweight men and records their weight before the trial. She then prescribes the supplement and instructs them to take it for four weeks while making no other lifestyle changes. After the four-week period, she records the weight of the men again. Identify the null and alternative hypotheses for a hypothesis test where d = weight after trial-weight before trial. Select the correct answer below:

A poll done for Newsweek found that 13% of Americans have seen or sensed the presence of an angel. A contingent doubts that the percent is really that high. It conducts its own survey. Out of 76 Americans surveyed, only two had seen or sensed the presence of an angel. As a result of the contingent’s survey, would you agree with the Newsweek poll? Perform a hypothesis test, using the five-step process, to test whether the proportion of Americans who have seen or sensed the presence of an angel is less than 13%.

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a= 0.01, (b) a = 0.05, and (c) α=0.10. P=0.1123 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? ve this OA. Fail to reject Ho because the P-value, 0.1123, is less than α = 0.01 OB. Reject Ho because the P-value, 0.1123, is less than α=0.01. OC. Fail to reject Ho because the P-value, 0.1123, is greater than α=0.01. OD Reject Ho because the P-value, 0.1123, is greater than a = 0.01. Get more help - Q Search 16 4- 6 17 W & J+ 00 * 90 00 f9 ( f10 Janette Z 187 x
