Question 2 When deciding whether to use a pooled or non-pooled T procedure for testing a hypothesis about two population means, one has to check whether the populations variances can be assumed to be equal or not. However, it can't be done just by looking at the sample variances. Although the sample variances may not appear to be exactly the same it can be due to the sampling error. We want to statistically check the claim whether the variances are the same or not. To check this claim, the two-tail F-test for two variances was setup and the p-value was calculated to be 0.007. Interpret the results using the significance level of 1% and decide whether to use a pooled or non-pooled T procedure to test a claim about the population means. Under 1% significance level, there is Select an answer 0 to suggest that the two populations have different variances, therefore, to test a claim about the population means we would use the T Select an answer 0 procedure.
In response to this, Garcia might say, as he sometimes does, that it is enough for Stephen to be a racist if his dislike is "racially based," That is, if he dislikes Andre because of Andre's racial designation. On this view, in order for Stephen's dislike of Andre to be racist, Stephen need not dislike him because of any beliefs he (Stephen) holds about "races" in general or about black people in particular, provided he makes a racial distinction "in his heart." But is this correct? Let's suppose that Peter X, a white but problack radical, has contempt for Andre because Peter believes that no selfrespecting black man committed to the black freedom struggle would be involved romantically with a white woman. Peter's contempt is directed at Andre because of Andre's "race," but in being contemptuous of him for this reason Peter would be simply echoing the sentiment of many blacks who believe that the cause of black liberation requires observing the rule of racial endogamy. Peter's contempt for Andre may be unjustified, but surely it is not racist, despite its being "racially based." Thus, the fact that a vicious attitude has a "racial basis" is not sufficient to ground the charge of racism; the exact nature of the corresponding racial beliefs will also be relevant. (It is perhaps also worth pointing out that Garcia's talk of making distinctions "within one's heart" is quite misleading, for surely our ability to discriminate on "racial" grounds is a cognitive capacity; and not a purely volitional one,)

The CEO of a multinational retail corporation has decided to raise the minimum wage for its U.S. employees to three times the current federal minimum wage. The CEO explains that the company needs to provide its employees a living wage, regardless of what the law requires. According to Milton Friedman, did the corporation fulfill its duty?

UNBROKEN that in 1. Reading Quiz Question 10 Instructions Order these events chronologically as they occur in the text: Available Options ( 5 of 5 ) Thirteen months after the Green Hornet crashed, Louie's family was informed by the military that he was dead. Louie and Phil were sent from Kwajalein to a POW camp in mainland Japan called Ofuna. Louie's family learned that their son was still alive after he spoke on the radio show Postman Calls. Louie beat a Japanese runner in a race at Ofuna, even though he knew he would be beaten for his victory. Watanabe, nicknamed "The Bird" at the POW camp at Omori, became fixated on making Loule's existence a living hell, calling him his "number one prisoner."

377 of the 627 freshmen psychology majors from a recent study changed their major before they graduated and 416 of the 611 freshmen business majors changed their major before they graduated. What can be concluded at the alpha=0.05 level of significance? If the calculator asks, be sure to use the "Pooled" data option. For this study, we should use z-test for the difference between two population proportions The results are statistically significant at alpha=0.05, so there is sufficient evidence to conclude that the proportion of the 627 freshmen psychology majors who changed their major is less than the proportion of the 611 freshmen business majors who change their major.

L. lactis bacteria may live on plants or in milk. These two environments contain different types or sugars. Plants contain polysaccharides but not lactose. Milk contains lactose but not polysaccharides. L. lactis are often best adapted to fermenting the sugar in their environment. So, L. lactis living on plants often have polysaccharide-specific fermentation, and L. lactis living in milk often have lactose-specific fermentation. Consider the population of L. lactis bacteria over the time period previously shown. Over this time period, bacteria with polysaccharide-specific fermentation were less likely to survive and reproduce than bacteria with lactose-specific fermentation. This means that having polysaccharide-specific fermentation was less advantageous than having lactose-specific fermentation.

For a standardized exam at your school, the mean score is 106.0 with a variance of 404.9. You have heard that student athletes are held to strict academic standards. Because of that, you want to know if the variance in test scores among student athletes, σ^2, is lower. To find out, you survey a random sample of 10 student athletes. You find the sample variance is 175.6. Assume test scores for student athletes follow a normal distribution. Is there sufficient evidence to conclude that the population variance, σ^2, is less than 404.9? To answer, complete the parts below to perform a hypothesis test. Use the 0.05 level of significance. (a) State the null hypothesis H0 and the alternative hypothesis H1 that you would use for the test. H0: H1: (b) Perform a chi-square test and find the p-value.
