Several years ago, the mean height of women 20 years of age or older was 63.7 inches. Suppose that a random sample of 45 women who are 20 years of age or older today results in a mean heightof 64.8 inches.(a) State the appropriate null and alternative hypotheses to assess whether women are taller today.(b) Suppose the P-value for this test is 0.06. Explain what this value represents.(c) Write a conclusion for this hypothesis test assuming an α = 0.05 level of significance.

The table to the right includes results from polygraph experiments. In each case, it was known if the subject lied or not, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truths and lies? State the null and the alternative hypotheses. Choose the correct answer below. O A. Ho: The row and column variables are independent. H₂: The row and column variables are dependent. OB. Ho: At least one of the values is different from the others. Ha: All values in the table are equal. OC. Ho: All values in the table are equal. Ha: At least one of the values is different from the others. Polygraph indicated that subject lied Polygraph indicated that subject did not lie O D. Ho: The row and column variables are dependent. H₂: The row and column variables are independent.

Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that 51.1% of newborn babies are boys. B. Reject Ho. There is sufficient evidence to warrant rejection of the claim that 51.1% of newborn babies are boys. O C. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that 51.1% of newborn babies are boys. D. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that 51.1% of newborn babies are boys. Do the results support the belief that 51.1% of newborn babies are boys? O A. The results support the belief that 51.1% of newborn babies are boys because there was no evidence to show that the belief is untrue. O B. The results do not support the belief that 51.1% of newborn babies are boys because there was sufficient evidence to show that the belief is untrue. OC. The results support the belief that 51.1% of newborn babies are boys because there was…

New Orleans' Coca Cola bottling center wants to determine whether the mean amount of product in a 12 oz can of Coke is actually 12 ounces. Thus, the null and alternative hypotheses are Ho: mu is equal to 12 ounces Ha: mu is not equal to 12 ouncesYou want to be extra sure that you aren't underfilling (which would open you up to a lawsuit). Being risk averse, you set out to conduct a hypothesis test at a stringent 99% level. Fill rates are distributed Normally. You take a sample of 50 different Coke cans and carefully measure the amount of product. From this sample, you calculate an avg fill of 12.3 ounces, with a standard deviation of 0.75 ounces. What do you conclude about the average amount of Coke product in the cans? Group of answer choices a. There is sufficient evidence to conclude that you are not filling to 12 ounces on average. b. There is NOT sufficient evidence to conclude that you are under- or over-filling on average.
Suppose are running a study/poll about the accuracy rate for fingerprint identification. You randomly sample 127 people and find that 89 of them match the condition you are testing. Suppose you are have the following null and alternative hypotheses for a test you are running: Ho: p = 0.72 H₁: p 0.72 Calculate the test statistic, rounded to 3 decimal places Question Help: Video Message instructor Post to forum Submit Question
For the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.) Researchers state 2.5 hours as the mean amount of television watched by children per night. One parent claims that the mean amount of television watched by children per night is less than 2.5 hours. The parent conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the mean amount of television watched by children per night is 2.3 hours. Was an error made? If so, what type?

Consider a drug testing company that provides a test for marijuana usage. Among 266 tested subjects, results from 27 subjects were wrong (either a false positive or a false negative). Use a 0.05 significance level to test the claim that less than 10 percent of the test results are wrong. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p0.1 O C. Ho: p= 0.1 H: p#0.1 O D. Ho: p=0.1 H:p<0.1 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.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O B. Reject Ho.

Q13. The null Hypothesis is rejected, if the P-value is larger than significance level.a. Trueb. False
After performing a hypothesis test, the p-value is p = 0.013. If the test was performed at a significance level of a = 0.046, should the null hypothesis be rejected? O a. Reject the null hypothesis since 0.013 0.046 O c. Reject the null hypothesis since 0.013 > 0.046 O d. Fail to reject the null hypothesis since 0.013 < 0.046
aps Microsoft Word -... 12) and 13) Hypothesis testing for proportions You must show your work: 1. Clearly state the significance level, sample size, sample proportion 2. Clearly state the null hypothesis and alternative hypothesis 3. Present the test statistics (z-score) and P-value 4. Decided if the null hypothesis should be rejected for the alternative or not. 5. Write out the conclusion to the question. ► The recidivism rate for convicted sex offenders is 15%. A warden suspects that this percent is higher if the sex offender is also a drug addict. Of the 320 convicted sex offenders who were also drug addicts, 58 of them became repeat offenders. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? Select an answer H₁: ? Select an answer ✓ c. The test statistic ? = d. The p-value = e.

a. If a null hypothesis is rejected with a significance level of 0.05, is it also rejected with a significance level of 0.01? Why or why not? Suppose the level of significance for carrying out the test is lowered from 5% to 1%. As a result, has the likelihood of rejecting the null hypothesis when it is true increased or decreased? Explain
