A researcher randomly sampled 30 graduates of an MBA program and recorded data about their starting salaries. Of primary interest to the researcher is whether starting salaries differ based on gender. The researcher performs a pooled-variance t-test of the mean salaries of the females (Population 1) andmales (Population 2) in the sample. Assume α = 0.10. What assumptions are necessary to conduct this hypothesis test? The samples were randomly and independently selected. Both populations of salaries (male and female) must have approximate normal distributions. The population variances are approximately equal.
Suppose we have a random sample of size n=100 drawn from a population with a mean of μ=50 and a standard deviation of σ=10. We want to test the null hypothesis H0: μ=48 against the alternative hypothesis H1: μ≠48 using a two-tailed test with a significance level of α=0.05. What is the decision and p-value of this hypothesis test?

A sample is selected from a population with population mean = 50. After a treatment is administered to the individuals in the sample, the mean is found to be M = 55 and the variance is s2 = 64.a. If the sample has n = 36 scores, then conduct the four steps of hypothesis testing to evaluate the significance of the treatment effect and calculate Cohen’s d to measure the size of the treatment effect. Use a two-tailed test with alpha level = .05.
Two different formulations of an oxygenated motor fuel are being tested to study their roadoctane numbers. The variance of road octane number for formulation 1 is σ1 2 = 1.5, and for formulation, 2 it is σ2 2 = 1.2 . Two random samples of size n1 = 15 and n2 = 20 are tested, andthe mean road octane numbers observed are x̅1 = 89.6 and x̅2 = 92.5. Assume normality.(a) If formulation 2 produces a higher road octane number than formulation 1, themanufacturer would like to detect it. Formulate and test an appropriate hypothesis using α =0.05.
A researcher measures weights of Rat A and Rat B, 8 animals from each of the species were weighed and 95% CI on the means of the weights was calculated. Length of CI of Rat A mean weight was 20 mm, length of CI of Rat B mean weight was 30. Which rat type has a more variant weight? Explain your answer. A hypothesis test was performed to test if variance of a dataset is different than 3.5 or not, by using α = 0.05. The dataset had 8 samples, and value of the test statistic was 20. What was the hypothesis, which test was used, was it rejected or accepted? 200 autistic children were given an IQ test. The researcher wants to compare their average IQ to IQ of the general public. Which hypothesis test should they use and why? Do you prefer to have high Type I error or high Type II error in your hypothesis test? Why?
Two pain-relieving drugs were compared for effectiveness on the basis of length of time elapsing between administration of the drug and cessation of pain. Thirteen patients received drug 1, and 13 received drug 2. The sample variances were = 64 and = 16. Test the null hypothesis that the two populations variances are equal. Let α = .05.
