Calculate the pooled variance.Explain why we use pooled variance. Stating that we need it for the standard error is not sufficient. Explain conceptually why the variation in the 2 groups is combined for the statistical test.What is the critical t and degrees of freedom for this test (assuming alpha = .05)?Calculate the obtained-t. There are hundreds of studies that demonstrate the effects of priming onhuman behavior. In one application, researchers have discovered thatcharacteristics of one's environment can influence behavior. To test theeffects of priming on ratings of job attitudes, a researcher designs a study tosee whether people report differing levels of work centrality (i.e. theimportance of work in a person's life) depending on whether they completetheir ratings while they are at work or while they are relaxing in a coffee shop.The researcher identifies 15 adult employees, and asks them to complete astandardized measure of work centrality (i.e. work importance) while they areworking at their workplace (Workplace Group). The researcher also identifiesa separate group of 20 adult employees, and asks them to complete the samework centrality measure while they are relaxing at a coffee shop (Coffee ShopGroup). The work centrality measure assesses the degree to whichparticipants believe that working is a central aspect of their lives. Scoresrange from 1-7, where higher scores indicate greater work centrality.Workplace (WP)_M = 6.5SS = 85Coffee Shop (CS).M = 4SS = 30

A researcher was interested in knowing if mean BMI was different between males and females. He obtained the following test results. Choose the correct interpretation of the results: F test p value = 0.03 Two sample t test, assume equal variance = 0.02 Two sample t test, assume unequal variance = 0.06 Mean BMI is higher in males than females. None Mean BMI is not significantly different between males and females. Mean BMI is significantly different between males and females.

The average score on a statistics test was 2.21 with a standard deviation of 0.88. The teacher suspects that the exam was very difficult; Based on the above, you want to adjust the scores so that the mean is 3.37 and the standard deviation is 0.25. Compute the values a and b such that the fit of type aX+b gives the desired mean and variance? Calculate: a= Answer b= Answer TIP: Use expected value and variance properties.
