The management of the Seaside Golf Club regularly monitors the golfers on its course for speed of play. Suppose a random sample of golfers was taken in 2005 and another random sample of golfers was selected in 2006. The results of the two samples are as follows: 2005 2006 x1= 225 x2= 219 s1= 20.25 s2= 21.70 n1= 36 n2= 31 Based on the sample results, can the management of the Seaside Golf Course conclude that the average speed of play was different in 2006 than in 2005? Conduct the appropriate hypothesis test at the 0.10 level of significance. Assume that the management of the club is willing to accept the assumption that the populations of playing times for each year are approximately normally distributed.
A sample of men and women who had passed their driver's test either the first time or the second time were surveyed, with the following results: Results of the driving testGender First time Second timeMen 126 211Women 135 178a) Do these data suggest that there is a relationship between gender and the passing of their driver’s test from which the present sample was drawn? Let alpha=.05

A developmental psychologist is studying bonding between healthy newborn babies and immediate family members. He wants to know if one-week-old infants use smell to recognize their fathers. To investigate, he selects a random sample of one-week-old infants. Each infant is presented with a garment worn by his or her father and two garments worn by unrelated men. The psychologist observes which garment each of the infants orients toward. The resulting data are summarized in the following table that shows the number of infants who oriented toward each of the three garments. What is are the degrees of freedom for this experiment? 4 3 1 2
TABLE 1 The director of cooperative education at a state college wants to examine the effect of cooperative education job experience on marketability in the work place. She takes a random sample of 4 students. For these 4, she finds out how many times each had a cooperative education job and how many job offers they received upon graduation. These data are presented in the table below. Student CoopJobs JobOffer 1 1 4 2 2 6 3 1 3 4 0 1 Referring to Table 1, set up a scatter plot with Coop Jobs as the horizontal axis and Job offer as the vertical axis

A random sample of 50 local citizens was polled. Use Sheet 4 of the Excel file linked above to calculate p^ and the 95% confidence interval. p^= Upper bound for 95% confidence interval = Lower bound for 95% confidence interval = The organization can say with 95% confidence that the true population proportion of the local population that lives within two miles of a grocery store is in the interval [_____,_____]. The lowest likely proportion is ____
Which New Jersey universities have students with higher GPAs? A researcher compares the GPA of 20 randomly selected students from each of the following 3 schools: Seton Hall, TCNJ, and Rowan. The mean GPAs were as follows: Seton Hall = 3.12, TCNJ = 3.39, Rowan = 2.90. (These are all made up, by the way.) SSwithin = 18.39 and SSbetween = 2.24. What can the researcher conclude at alpha .05?

Miller (2008) examined the energy drink consumption of college undergraduates and found that males used energy drinks significantly more often than females did. To further investigate this phenomenon, a researcher selects a random sample of n = 36 male undergraduates and a sample of n = 25 females. On average, the males report consuming M = 2.45 drinks per month, and females have an average of M = 1.28. Assume that the overall level of consumption for college undergraduates averages μ = 1.85 energy drinks per month and that the distribution of monthly consumption scores is approximately normal with a standard deviation of σ = 1.2. Did this sample of males consume significantly more energy drinks than the overall population average? Use a one-tailed test with α = .01. Use the Distributions tool to help you find the critical values. The null hypothesis is H₀: . For the sample of males, the standard error is σMM = , and z =, which is the critical value of .…
