- The president of a university is in need of an academic vice president and wants the approval of more than 50% of the faculty for his candidate. He wants statistical significance and the absolute value. Out of 120 randomly selected faculty members, 65 approved. Is this sufficient to appoint the candidate? Use 0.05 level of significance. Write the research hypothesis Determine the critical region and z-value Whats the decision?State the null and the alternative hypothesis. Determine the level of significance. Select the appropriate test statistic and compute the value. Compare the value of the test statistic and the critical value obtained from alpha. Make a decision interpret the resultplease calculate the test statistic please calculate the critical value Is there sufficient evidence. at the 0.05 level of significance, what is the upper-tail critical value from Studentized range distribution? at the 0.01 level of significance, what is the upper-tail critical value from Studentized range distribution? To perform the Tukey-Kramer procedure, what is the critical range?
- Researchers wanted to measure the effect of alcohol on the development of the hippocampal region in adolescents. The researchers randomly selected 11 adolescents with alcohol use disorders. They wanted to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm3. An analysis of the sample data revealed that the hippocampal volume is approximately normal with x=8.23 and s=0.9. Conduct an appropriate test at the α=0.05 level of significance. What is the hypothesis?, What is the test statistic? What is the P value? What conclusion can be drawn?Compute value of test statistic x^2 Identify the critical value does the data provide sufficient evidence that the distribution of the variable differs from the given distribution? thanks!Give two example to explain the Interval Estimation & Hypothesis for two samples. Discuss the Hypothesis case 3 with P-value and critical approach

- A sample mean, sample size, and population standard deviation are given. Use the one-mean z-test to perform the required hypothesis test at the given significance level. Use the critical value approach. (A) Calculate the test statistic (clearly label it as either z or t as needed); (2) Embed a photo of a manual sketch of the distribution with the critical region(s) shaded and the test-statistic clearly labeled; (3) Determine whether to reject or fail to reject H0, (4) Write a conclusion based on the rejection or failure to reject H0. All math must be typeset appropriately using the Rich Text Editor. You must embed the sketch of the critical region within the Rich Text Editor adhering to the Photo Upload Guidelines.= 25, n = 40, σ = 1.5, H0: μ = 22Ha: μ ≠ 22 **claim** α = 0.05normal death rate for patients with extensive burns (more than 40% of skin area) has been significantly reduced by the use of new fluid plasma compresses. Before the new treatment, the mortality rate for extensive burn patients was about 60%. Using the new compresses, the hospital found that only 41 of 89 patients with extensive burns died. Use a 1% level of significance to test the claim that the mortality rate has dropped since using the new treatment.What are we testing in this problem? A. single mean b. single proportion What is the level of significance?State the null and alternate hypotheses. H0: ? ≤ 0.6; H1: ? > 0.6 H0: ? ≥ 0.6; H1: ? < 0.6 H0: p ≥ 0.6; H1: p < 0.6 H0: p = 0.6; H1: p ≠ 0.6 H0: p ≤ 0.6; H1: p > 0.6 H0: ? = 0.6; H1: ? ≠ 0.6 What sampling distribution will you use?
