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?
10% of all Americans suffer from sleep apnea. A researcher suspects that a higher percentage of those who live in the inner city have sleep apnea. Of the 302 people from the inner city surveyed, 36 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.05? 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 larger than 10% at αα = 0.05, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is equal to 10%. The data suggest the population proportion is not…
You collect N = 200 frogs from a pond and find that 120 of them are female. You wish to conduct the following hypothesis test (α = 0.05) for p (the proportion of female frogs in the pond): H0 : p = 0.55 HA : p > 0.55 Determine which of the following statements are true. Assume the true p = 0.65. I. The one-sided p-value is 0.1528. II. You reject the null hypothesis H0. III. You fail to reject H0 and make a Type II error. Group of answer choices I and III only III only I only None of the Above II only
If the α-level (alpha level) is made larger, then: Group of answer choices The P-value will be smaller, as well. The hypothesis test will most likely be two-sided. The null hypothesis is less likely to be rejected. The null hypothesis is more likely to be rejected.

You watch people exiting Dodgers stadium after a game and you write down the number of males and the number of females that exit the stadium past you during the 20 minutes that you spend watching. You assumed that there would be a perfectly equal number of males and females attending a Dodgers game, but you look at the number of males and females that you actually counted, and you see if you still think that is actually true. What kind of hypothesis test would allow you to do this? a. One-Factor, Independent-Measures ANOVA b. Two-Factor ANOVA c. Correlation/Regression d. Chi-Square Goodness of Fit
A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 68%. 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 H, and the alternative hypothesis H that we would use for this test. H: 0 O
Only 19% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 363 randomly selected registered voters surveyed, 91 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 The null and alternative hypotheses would be: H0:H0: _______ (please enter a decimal) H1:H1: ________ (Please enter a decimal)
What is the 99% confidence interval? What is the Test Statistic? What is the two-tailed p-value of the result?
In a random sample of 80 Americans, 55% wished that they were rich. In a random sample of 100 Europeans, 48% wished that they were rich. At α=0.10α=0.10 is there a difference in the proportions? What is your decision? Accept the alternative hypothesis. Fail to reject the null hypothesis. Reject the null hypothesis. Accept the null hypothesis
Suppose a group of 800800 smokers (who all wanted to give up smoking) were randomly assigned to receive an antidepressant drug or a placebo for six weeks. Of the 500500 patients who received the antidepressant drug, 134134 were not smoking one year later. Of the 300300 patients who received the placebo, 5151 were not smoking one year later. Given the null hypothesis ?0:(?1−?2)=0H0:(p1−p2)=0 and the alternative hypothesis ??:(?1−?2)≠0Ha:(p1−p2)≠0, conduct a test to see if taking an antidepressant drug can help smokers stop smoking. Use ?=0.03α=0.03 (a) The rejection region is |?|>|z|> (b) The test statistic is ?=z=
