A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.67, but given the number of people you've talked to about this same issue, you believe it is less than 0.67. If you conduct a hypothesis test, what will the null and alternative hypotheses be?   Question 1 options:   1)  HO: p ≤ 0.67 HA: p > 0.67   2)  HO: p = 0.67 HA: p ≠ 0.67   3)  HO: p < 0.67 HA: p ≥ 0.67   4)  HO: p ≥ 0.67 HA: p < 0.67   5)  HO: p > 0.67 HA: p ≤ 0.67

A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 72% . Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0 :   H1 :

Please answer sub-parts 4,5, and 6 You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly smaller than 53% at a level of significance of αα = 0.01. According to your sample, 44 out of 98 potential voters prefer the Democratic candidate. For this study, we should use     The null and alternative hypotheses would be:     Ho:            (please enter a decimal)    H1:            (Please enter a decimal) The test statistic     =  (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      the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly smaller than 53% at αα = 0.01, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 53%. The data suggest the populaton proportion is significantly…

According to the most recent General Social Survey, 70% of adults watch TV nightly. A researcher believes that the proportion of college students who watch TV nightly is less than this. To test this claim the research samples 400 college students and finds that 276 watch TV nightly. At the 0.05 level of significance does this data provide evidence to suggest that the proportion of college students who watch TV nightly is less than 70%? Select the correct conclusion for the hypothesis test:   Question 12 options:   Fail to reject the null hypothesis because the p-value is less than the level of significance.   Fail to reject the null hypothesis because the p-value is greater than the level of significance.   Reject the null hypothesis because the p-value is less than the level of significance.   Reject the null because the p-value is greater than the level of significance.

Part C: Perform a chi-square test for the hypotheses. H0: The number of courses enrolled by students at the local college and their employment status have no association.Ha: The number of courses enrolled by students at the local college and their employment status have an association. What can you conclude based on the p-value?

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

SECTION 10.3 Step 1 of 3 : State the null and alternative hypotheses for the test. Fill in the blank below. Step 2 of 3 :Compute the value of the test statistic. Round your answer to three decimal places. Step 3 of 3: Do we reject the null hypothesis? Is there sufficient or insufficient data?

53% of students entering four-year colleges receive a degree within six years. Is this percent larger than for students who play intramural sports? 161 of the 283 students who played intramural sports recelved a degree within six years. What can be concluded at the level of significance of a = 0.05? a. For this study, we should use Select an answer b.
