Why would the null hypothesis not be the mean lifespan of sexually inactive males (62.5)?

QUESTION 5 What is iny 0.8944)? (Use the normal tables and report to two digits.) QUESTION 6 What is 0inyl 0.9878)? (Use the normal tables and report to two digits.)

Suppose that the scores on a reading ability test are normally distributed with a mean of 65 and a standard deviation of 9. what proportion of individuals score at most 52 points on this test? Round your answer to at least four decimal places. ?

A December 2014 Pew Research Center poll asked a sample of 1507 adults whether they thought it was important to control gun ownership. A total of 693 of the poll respondents were in support of controls on gun ownership. (a) It the past it was believed that p = 0.48. Test this claim at the a = 0.05 level of significance. Ho: HA: Test Statistic: p-value: Conclusion:

It is believed that nearsightedness affects about 8% of all children. In a random sample of 220 children, 26 are nearsighted.(a) Construct hypotheses appropriate for the following question: do these data provide evidence that the 8% value is inaccurate? __Ho: p = .08Ha: p > .08 __Ho: p = .08Ha: p < .08 __Ho: p = .08Ha: p ≠ .08 (b) What proportion of children in this sample are nearsighted? _______ (round to four decimal places)(c) Given that the standard error of the sample proportion is 0.0195 and the point estimate follows a nearly normal distribution, calculate the test statistic. Z = _______ (round to two decimal places)(d) What is the p-value for this hypothesis test? P-value = __________ (round to four decimal places) (e) What is the conclusion of the hypothesis test? Since p ≥ α we do not have enough evidence to reject the null hypothesis Since p<α we reject the null hypothesis and accept the alternative Since p ≥ α we accept the null hypothesis Since p ≥ α we reject…

Please help me find the standardized test statistic and the P-value

You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly more than 0.81. Thus you are performing a right-tailed test. Your sample data produce the test statistic z=2.845. Find the p-value accurate to 4 decimal places. p-value =
