can you explain how these scores were found, based on the statistics provided they dont seem to match up.' There is a significant interaction effect between employment status and substance use on stress levels. Two-Way ANOVA result: F(3,470) = 5.67, p = 0.001' I
You want to determine if diet impacts body weight. You recruit 60 subjects, assigning 20 each to either one of two dietary interventions or to maintain their normal diet. You measure body weight before and after the intervention and calculate the change in body weight (post minus pre weights). To determine the diet effect on the calculated change in body weight, you would use a .Assume all assumptions are met for a parametric test.

Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 101.16, y = 102.3, r= 0.810, P-value = 0.000, and y = 23.09+0.78x, where x represents the IQ score of the wife.

Should there be a significant difference with this study, what post-hoc test shall be used? Dr. Hess has done work that suggests that emotional arousal affects pupil size. To ascertain if the type of arousal makes a difference, you decided to measure pupil size under three different arousal conditions (Neutral, Pleasant, Aversive). Each participant will look at all the different pictures that differ according to the condition. The pupil size after viewing each photograph is measured in millimeters. * t-Test paired two sample for means O t-Test assuming equal variances O t-Test assuming unequal variances

Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 42 passengers, and a flight has fuel and baggage that allows for a total passenger load of 7,056 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 7,056 lb42=168 lb. What is the probability that the aircraft is overloaded? Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 178.3 lb and a standard deviation of 36.8.
Food deserts have become a particularly hot topic in the public health community as anexplanation for a variety of negative health outcomes in disadvantaged areas. Aresearcher is interested in comparing the average shelf space provided by supermarkets,convenience stores, and corner stores in two different communities in order to address thegrowing concern for food deserts. Assume the following table reports the summary statistics for shelf space dedicated to fresh fruits and vegetables (meters) obtained from SRSs of a variety of different stores that supply groceries from each community.
