A sample is selected from a population with μ= 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. For a sample of n = 4 scores, conduct a hypothesis test 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 α = .05. b. For a sample of n = 16 scores, conduct a hypothesis test 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 α = .05.1.State hypotheses 2.Locate critical region using the t-table, df, and alpha3.Calculate t-statistic 4.Make a decision regarding Ho (null hypothesis) c. Describe how increasing the size of the sample affects the likelihood of rejecting the null hypothesis and the measure of effect size.

A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.34. A dietician is asked to test this claim and finds that a random sample of 16 servings has a variance of 1.22. At α=0.05, is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed. Complete parts (a) through (e) below.
In a test of H0: µ=75 against HA: µ<75, a sample of size 450 produces Z = -1.19 for the value of the test statistic. Thus the p-value is approximately equal to:
