Consider a drug testing company that provides a test for marijuana usage. Among 335 tested subjects, results from 30 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 altenative hypotheses for this test. Choose the correct answer below. O A. Ho: p=0.1 H1: p#0.1 O B. Ho: p= 0.1 H: p0.1 O D. Ho: p<0.1 H1: 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. dentify 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. There is not sufficient evidence to warrant support of the claim…
I would like to know is my calculated answer correct
A researcher wants to test whether there is a difference in test scores between two groups. Which hypothesis should be the null hypothesis? a. There is a difference in test scores between the two groups. Ob. There is no difference in test scores between the two groups. Oc. The test scores of the two groups are positively related. Od. The test scores of the two groups are negatively related.
Find the value of the standard score, z, and determine whether to reject the null hypothesis at a 0.10 significance level. Is the alternative hypothesis supported? Ho: p= 19.6 seconds, H: p> 19.6 seconds, n = 121, x=20 5 seconds, o = 2.0 seconds a The value of the standard score is (Round to two.decimal places as needed.)
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. Did the subject…
In 2011, a U.S. Census report determined that 52% of college students are working students. A researcher thinks this percentage has changed and surveys 182 college students. The researcher reports that 106 of the 182 are working students. Is there evidence to support the researcher's claim at the 1% significance level? a. Determine the null and alternative hypotheses. Ho:p = H1: p ?V (Select the correct symbol and enter the value.) b. Determine the test statistic. Round to two decimal places. c. Find the p - value. Round to four decimal places. p- value = d. Are the results statistically significant? O Fail to reject the null hypothesis. O Reject the null hypothesis. e. Write the conclusion. O There is not sufficient evidence to support the claim that the percentage of working college students has changed. O There is sufficient evidence to support the claim that the percentage of working college students has changed.

A college counselor wants to perform the hypothesis test H0 : p = 0.50, Ha: p > 0.50, where p is the proportion of undergraduate students who eat breakfast. In a sample of 446 students, 246 ate breakfast. What is the P-value for this hypothesis test? a .0147 b .9853 c .552 d .448
