Researchers hypothesired that sex differences (male/female) would exist for scores on the WAIS Digit Spar Forwards testFor this test, the examinee is read a sequence of numbers and must recall the numbers in the same order. This testmeaures memory, with low scores indicating poor memory skill p 268 (assume alpha 05 for all analyses)Which of the following is the best description of the independent variatle or classification variable (note: if two wayANOVA is the appropriate analysis for the description, seleat BOTH independent variables)?O sexO examineeO total number of participants in each categoryO malesO femalesO researchersO WAS Digit Span Forwards test scoresO poor memory skillO age of the participantResearchers were interested in whether differences existed in WAIS Similarities test scores betweenthree zygosity groups: monozygotic (identical) twins, dizygotic (fraternal) twins, and non-twinsiblings. For the WAIS Similarities test, the examinee is presented with two words that representcommon objects or concepts and must describe how they are similar. This test measures verbalconcept formation and reasoning, with low scores indicating poor skills in these areas. p-12(assume alpha - 05 for all analyses).entsWhich of the followirng is the best description of the dependent variable (note if correletion or regression is theappropriate analysis for this description, select BOTH the X and Y variables)?O WAIS Similarities test scoresO number of participantsO dizygotic twinsO non-twin siblingsO the examineeO poor skillsO sex differencesO Yygosity groupsO wordsO monorygotic twinsO age of the participantO the researchers

A random sample of 100 rich men faculty and 100 rich women faculty at a Premier University is asked if they have an automobile on campus. If 31 of the rich men and 24 of the rich women have cars, can we conclude that more men than women have cars on the campus? Use a 0.01 level of significance.
An auditor for a local court system is tasked with comparing the rulings of two judges. The auditor needs to determine if Judge Hughes issues shorter sentences than Judge Wilson. The data below are the sentence lengths, in months, issued by each judge in their last twelve cases that dealt with operating a motor vehicle without a license. Test the claim that Judge Hughes issues shorter sentences than Judge Wilson for this particular type of case at the 0.10 level of significance. Let Judge Hughes' sentences be Population 1 and let Judge Wilson's sentences be Population 2. Assume that both populations are approximately normal and that the population variances are equal.

Winning team data were collected for teams in different sports, with the results given in the accompanying table. Use a 0.05 significance level to test the claim that home/visitor wins are independent of the sport. Given that among the four sports included here, baseball is the only sport in which the home team can modify field dimensions to favor its own players, does it appear that baseball teams are effective in using this advantage? Click the icon to view the data table. Determine the null and alternative hypotheses. Choose the correct answer below. A. Ho: Basketball games are more likely to win at home than any other sport. H₁: Basketball games are not more likely to win at home than any other sport. OB. Ho: The home/visitor win is independent of the sport. H₁: The home/visitor win is not independent of the sport. OC.

Researchers were interested in assessing whether stress levels are different at the beginning of the semester compared to finals week. To test this, stress was measured in 5 students at the start of the semester and then again at the end of the semester during finals week.

The first question in in the second picture gets a little cut off, it says "the test statistic for this is ___". Thank you!
The General Social Survey is an annual survey given to about 1500 U.S. adults selected at random. A recent survey contained the question "How important to your life is having a fulfilling job?" Of the 267 college graduates surveyed, 106 chose the response "Very important." Of the 113 people surveyed whose highest level of education was high school or less, 59 chose the response "Very important." Based on these data, can we conclude, at the 0.05 level of significance, that there is a difference between the proportion p1 of all U.S. college graduates who would answer "Very important" and the proportion p2 of all U.S. adults whose highest level of education was high school or less who would answer "Very important"?Perform a two-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary, consult a list of formulas.) A. Find the value of the test statistic and round to…
any studies have been conducted to test the effects of marijuana use on mental abilities. In one such study, groups of light and heavy users of marijuana in college were tested for memory recall, with the results given below. Use a a 0.05 significance level to test the claim that in the population of heavy marijuana users, the mean number of items sorted correctly is lower than the mean number in the population of light users. Items sorted correctly by light marijuan users: n = 64, x overbar equals 53.5 , s = 3.6 Items sorted correctly by heavy marijuan users: n = 65, x overbar equals 51.3 , s = 4.5 a. Define the parameters A. p 1 equals The proportion of light marijuana users p 2 equals The proportion of heavy marijuana users B. mu 1 equals The mean number of light marijuana users mu 2 equals The mean number of heavy marijuan users C. p 1 equals The proportion of items sorted correctly by all light…
We ask if visual memory ability for a sample of 25 art major (x=49) is better than that of engineers who, on a nationwide test, scored µ=45 and ox=14. Higher scores indicate a bettermemory. а. Is this a one- or two-tailed test? b. What are H, and H.? с. Perform the z-test.
