Discuss whether the following hypothesis is a good hypothesis (i.e., they are logical, testable, refutable, and positive). Specifically say whether if it is logical, testable, refutable, and positive. If so, why? If not, why not? People who pray regularly are less likely to be injured in an accident

Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A report claims that more than 83% of households in a specific county struggle to afford basic necessities. Does the claim represent the null hypothesis or the alternative hypothesis? a statement of equality, it represents the Since the claim hypothesis.

The National Association of Realtors reported that 26% of home buyers in the state of Florida are foreigners in 2012. The correct hypothesis statement to test the validity of this report would be a. O b. O c. d. H0: p = 0.26; H1: p + 0.26. H0: p = 0.26; H1: p > 0.26. H0: p = 0.26; H1: p < 0.26. H0: p = 0.26; Hl: p = 0.26.

Which hypothesis represents the statement of "no change" (or "no affect/difference"),  that we assume to be true?  A.The one hypothesis, H1   B.The null hypothesis, H0   C.The right hypothesis, H0   D.The alternative Hypothesis, H1

If in a population 60% of people own an iPhone, 45% of people own an Android phone, and 37% own both types of phone. Are "owning an iPhone" and "owning an Android" independent outcomes? Cannot tell from the given information. Yes, they are independent. No, they are dependent.

Which set of numbers would correspond to a hypothesis test with the greatest power? Cohen's d = 0.6 & n = 500 O Cohen's d = 0.6 & n = 50 O Cohen's d = 0.5 & n = 50 O Cohen's d = 0.5 & n = 500

In hypothesis testing, if the test statistic falls in the critical region then we reject the null hypothesis. a. Trueb. False

20. Which of the following is a null hypothesis?   a. Pregnant women who drink cranberry juice will have lower urine bacterial counts than those who do not drink cranberry juice. b. The urine bacterial count of pregnant women who drink cranberry juice will be lower or equal to that of pregnant women who do not drink the juice. c. There will be a difference between ingestion of cranberry juice and among pregnant women who do and do not have high urine bacterial counts.

Explain the meaning of each of the following in the context of hypothesis testing. a. α b. β c. 1 − β

Suppose that in a random selection of 100 colored candies, 23% of them are blue. The candy company claims that the percentage of blue candies is equal to 25%. Use a 0.05 significance level to test that claim. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho:p=0.25 H1:p>0.25 О В. Но: р#0.25 H1:p=0.25 Ос. Но р-0.25 H1:p<0.25 O D. Ho: p= 0.25 H1:p#0.25 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.)
