(a) The test is to check whether the number of days per week a member utilizes the health club's facilities is independent of their gender or not. The hypothesis is, Null hypothesis: H0: The number of days per week a member utilizes the health club's facilities is independent of their gender. Alternative hypothesis: H1: The number of days per week a member utilizes the health club's facilities is dependent of their gender. The row and column totals are, 0-1 2-3 4-5 6-7 Total Male 43 91 32 7 173 Female 35 68 21 3 127 Total 78 159 53 10 300 The expected values are, 0-1 2-3 4-5 6-7 Total Male 173×78300=44.98 173×159300=91.69 173×53300=30.56 173×10300=5.77 173 Female 127×78300=33.02 127×159300=67.31 127×53300=22.44 127×10300=4.23 127 Total 78 159 53 10 300 The test statistic is, χ2=Sum ofObserved-Expected2Expected=43-44.98244.98+91-91.69291.69+32-30.56230.56+7-5.7725.77+35-33.02233.02+68-67.31267.31+21-22.44222.44+3-4.2324.23=0.087+0.005+0.068+0.264+0.119+0.007+0.092+0.359=1.001 The test statistic is 1.001. The degrees of freedom is, df=r-1c-1=2-14-1=3 The degrees of freedom is 3. Computation of P-value: The P-value of χ2-distribution for test statistic 1.001 at 3 degrees of freedom can be obtained using the excel formula “=CHISQ.DIST.RT(1.001,3)”. The P-value is 0.8010. Decision rule: If P-value ≤α, then reject the null hypothesis. Otherwise, do not reject the null hypothesis. Conclusion: The P-value (0.8010) is greater than the level of significance (0.05). Based on decision rule, fail to reject the null hypothesis. Thus, it can be concluded that the number of days per week a member utilizes the health club's facilities is independent of their gender.(b) Based on the result obtained, the health club manager should conclude that there is no relation between gender and number of days per week that members utilize the club facilities.

(b) Based on this result, what should the health club manager conclude about the relationship between gender and the number of days per week that its members utilize the club's facilities?

2. In a study of parents' feelings about a required course in consumer education taught to their children, a random sample of 360 parents are classified according to whether they have one, two or more children in the school system, and also whether they feel that the course is poor, adequate or good. The results are shown in the table to the right. Test at the 0.05 level of significance whether there is a relationship between parents' reaction to the course and the number of children they have in the school system.

Attractiveness of body types has been a large discussion relating to effects on youth and culture. Unhealthy levels of BMI are often associated with beauty. A researcher decided to study how young heterosexual adults body type preferences related to BMI. Participants were asked to use a computer program to design their desired partner. The program then calculated the BMI of the designed partners. The table summarizes the results based on a SRS of 35 men and 48 women. BMI designed by men n=35 x-bar=18.850 stdev=1.750 SE Mean 0.277 BMI designed by women n=48 x-bar=25.860 stdev=4.215 SE Mean 0.625 Use this information to conduct a test to decide if male and/or female body type preferences are associated with healthy BMI measurements. You should have two complete tests here. You may assume the populations are normally distributed.
In 1990, 58% of Americans 18 years old and older reported they have a great deal of concern regarding air pollution. A recent poll found that 592 of 1004 Americans 18 years old or older stated that they have a great deal of concern regarding the level of air pollution in American. Is there evidence to conclude that the current proportion of Americans having a great deal of concern about the level of air pollution in America is different from the 1990 proportion, with a 10% level of significance? State the null hypothesis, alternative hypothesis, test statistic, p-value and conclusion.
Bank of America's Consumer Spending Survey collected data on annual credit card charges in seven different categories of expenditures: transportation, groceries, dining out, household expenses, home furnishings, apparel, and entertainment (U.S. Airways Attache, December 2003). Using data from a sample of 42 credit card accounts, assume that each account was used to identify the annual credit card charges for groceries (population 1) and the annual credit card charges for dining out (population 2). Using the difference data, the sample mean difference was = $844, and the sample standard deviation was sd = $1,166. C) What is the point estimate of the difference between the population means? $ What is the 95% confidence interval estimate of the difference between the population means (to the nearest whole number)?

Exercise is known to produce positive psychological effects. Interestingly, not all exercise is equally effective. It turns out that exercising in a natural environment (e.g., jogging in the woods) produces better psychological outcomes than exercising in urban environments or in homes (Mackay & Neill, 2010). Suppose that a sports psychologist is interested in testing whether there is a difference between exercise in nature and exercise in the lab with respect to post-exercise anxiety levels. The researcher recruits n 5 7 participants who exercise in the lab and exercise on a nature trail. The data below represent the anxiety scores that were measured after each exercise session. Treat the data as if the scores are from an independent-measures study using two separate samples, each with n 5 7 participants. Compute the pooled variance, the estimated standard error for the mean difference, and the independent-measures t statistic. Using a 5 .05, is there a significant difference…
2.- The journal Behavioral Research in Accounting published a study of Machiavellian traits in accountants. Machiavellian describes negative character traits that include manipulation, cunning, duplicity, deception, and bad faith. A questionnaire by email was administered to a random sample of 700 accounting alumni of a large southwestern university; however, due to nonresponse and incomplete answers, only 198 questionnaires could be analyzed. Several variables were measured, including age, gender, level of education, income, job satisfaction score, and Machiavellian (“Mach") rating score. The research findings suggest that Machiavellian behavior is not required to achieve success in the accounting profession. a) What is the populatidn of interest to the researcher? Answer: Business accountants in the southwest Accountants in general Accounting alumni from this university Business alumni from this university b) What inference was made by the researcher? Answer: Accountants are always…
The National Collegiate Athletic Association (NCAA) measures the Graduation Success Rate (GSR), which is the percentage of eligible athletes who graduate within six years of entering college. According to the NCAA, the GSR for all scholarship athletes in a particular division is 64%. The GSR for all students in this division is 61%. Suppose the NCAA report was based on a sample of 1,000 student-athletes, of which 640 graduated within six years. Is this sufficient information to conclude that the GSR for all scholarship athletes in this division differs from 61%? Carry out the test using a Type I error rate of 0.05.

In determining the best companies to work for, a number of variables are considered, including size, average annual pay, and employee turnover rate. Moreover, employee surveys are conducted to assess aspects of the organization's culture, such as trust and openness to change. In an attempt to determine what affects turnover rate, a sample of 33 companies was randomly selected, and data were collected on the average annual bonus and turnover rate (%) for 2008. In addition, a questionnaire was administered to the employees of each company to arrive at a trust index (measured on a scale of 0-100). Below are the multiple regression results.
