7. The distribution of diastolic blood pressures for the population of female diabetics between theof 30 and 34 has an unknown mean µ, and standard deviation o9.1 mm Hg. It may beagesuseful to physicians to know whether the mean of this population is equal to the mean diastolicblood pressure of the general population of females in this age group, 74.4 mm Hg.(a) What is the null hypothesis of the appropriate test?(b) What is the alternative hypothesis?(c) A sample of ten diabetic women is selected; their mean diastolic blood pressure is xa81 mm Hg. Using this information, conduct a two-sided test at the a = 0.05 level of sig-nificance. What is the p-value of the test?(d) What conclusion do you draw from the results of the test?(e) Would your conclusion have been different if you had chosen a = 0.01 instead of a = 0.05?

Given that Sample size n = 10 Sample mean = 81 Population SD = 9.1 Levelnof significance = 0.05 Note…

A study was conducted to investigate drinking problems among college students. In 1983, a group of students were asked whether they had ever driven an automobile while drinking. In 1987, after the legal drinking age was raised, a different group of college students was asked the same question. The results are as shown in the table below. Test to compare the proportions of students with a drinking problem at 0.05 level of significance, 1987 versus 1983; and provide the chi-squared statistic value below (in 2 decimal places).

A severe storm has an average peak wave beight of 16,4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating. Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down or getting worse. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis? Is the P-value area on the left, right, or on both sides of the mean? O H:a is less than 16.4 feet; the P-value area is on the left of the mean O H:u is less than 16.4 feet; the P-value area is on the right of the mean O H: u is greater than 16.4 feet; the P-value area is on the right of the mean OH:u is not equal to 16.4 feet: the P-value area is on the left of the mean OH : u is not cqual to 16.4 feet; the P-value area is on the right of the mean

14% of all Americans suffer from sleep apnea. A researcher suspects that a lower percentage of those who live in the inner city have sleep apnea. Of the 359 people from the inner city surveyed, 43 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.05? 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: Ho: ? μ p Select an answer = ≠ > < (please enter a decimal) H1: ? p μ Select an answer < > = ≠ (Please enter a decimal) The test statistic ? t z = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? > ≤ αα Based on this, we should Select an answer reject fail to reject accept the null hypothesis.

I asked this question yesterday and the answer was incorrect. Please see previous responses below that were incorrect for your reference. Thanks again! β = 0.4091 α = 3.1455 The lineal regression equation is y = 3.1455 +0.4091 x (second screenshot is the second step to the question that I received yesterday as well)
