The graph portrays the decision criterion for a hypothesis test for a population mean. The null hypothesis is H,: u=Hn. The curve is the normal curve for thetest statistic under the assumption that the null hypothesis is true. Use the graph to solve the problem.

Perform an independent-measures (samples) t-test in SPSS to determine if the starting salary (Variable "salary" "Starting Salary") of males is significantly higher than the starting salary of females. Use α = .01. p-value .0005 T-statistics 3.45 This is a one-tailed test because we are interested in whether the salary of one group is significantly greater than the salary of the other group Our assumption is this correct ? We reject the null because because .0005 is less than .01 and conclude male salary is greater than female salary ? or it is not greater ?
Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (μ, p, σ) for the indicated parameter. The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, μ, of 48° F, ideal for a certain type of German pilsner. The owner of the brewery does not agree with the refrigerator manufacturer, and claims he can prove that the true mean temperature is incorrect. Group of answer choices H0 : μ ≤ 48°H1 : μ > 48° H0 : μ ≥ 48°H1 : μ < 48° H0 : μ ≠ 48°H1 : μ = 48° H0 : μ = 48°H1 : μ ≠ 48°
Dentists A toothpaste company wants to declare in an ad that more than 80% of dentists recommend their toothpaste. The company performs a hypothesis test at the α = 0.05 significance level to test their claim. The company samples 800 dentists. Of these, 653 recommend their toothpaste. Let p represent the population proportion of dentists that recommend their toothpaste. b.Calculate the z or t statistic. (Do not use continuity correction. Round final answer to 4 decimal places) Statistic: c. Find the p-value. (Do not use continuity correction. Round final answer to 4 decimal places) p-value:
