With 0.05 significance level, H1: p > 0.5, and the value of test statistics is z = 1.25. Then the P-value is equal to 0.8944 -0.1056 0.1056 None

The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65-74 years: n = 117, x = 12.2, and s = 6.60. Does this data indicate that average daily zinc intake in the population of all males age 65-74 falls below the recommended allowance? (Use a = 0.05.) State the appropriate null and alternative hypotheses. Ο H, μ 15 Ha: u > 15 Ho:H = 15 Ha: u < 15 Ο H: μ= 15 H: u + 15 Ο H: μ= 15 H3: Hs 15 Calculate the test statistic and determine the P-value.

An independent-measures study comparing two treatment conditions with n = 6 in each sample produces t = 4.00. What is the value of r2 for this study?

Are Republicans less likely than Democrats to display the American flag in front of their residence on the Fourth of July? 425 of the 659 Republicans surveyed display the flag on the Fourth of July and 538 of the 784 Democrats surveyed display the flag on the Fourth of July. What can be concluded at the αα = 0.01 level of significance?

You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 0.25. You use a significance level of α=0.01α=0.01.      H0:p=0.25H0:p=0.25      H1:p≠0.25H1:p≠0.25You obtain a sample of size n=687n=687 in which there are 143 successes.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value =

Only about 10% of all people can wiggle their ears. Is this percent different for millionaires? Of the 381 millionaires surveyed, 27 could wiggle their ears. What can be concluded at the αα = 0.10 level of significance? For this study, we should use Select an answer z-test for a population proportion t-test for a population mean  The null and alternative hypotheses would be:  H0:H0:  ? p μ  Select an answer ≠ > < =   (please enter a decimal)  H1:H1:  ? p μ  Select an answer = > ≠ <   (Please enter a decimal) The test statistic ? t z  =  (please show your answer to 3 decimal places.)

Thus, the final conclusion is that ... The data suggest the population proportion is not significantly different from 10% at αα = 0.10, so there is statistically insignificant evidence to conclude that the…

The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65-74 years: n = 113, x = 12.4, and s = 6.63. Does this data indicate that average daily zinc intake in the population of all males age 65-74 falls below the recommended allowance? (Use a = 0.05.)
