Daniel Goleman, Ph.D., is an author, psychologist, and science journalist specializing in psychology and brain sciences. Goleman developed the argument that E.I. (emotional intelligence) can matter as much as I.Q. for workplace success, and for leadership effectiveness. Emotional intelligence does not mean being emotional. According to Goleman, E.I. means being skillful in the emotional and science realm. Goleman states that emotions are contagious. Recall a time in the workplace where this statement has or has not happened. Also, given what you have read this week in the textbook on perception and individual differences, discuss your reactions to Goleman’s assertions.

The sampling distribution of the sample mean for a sample of 50 elements taken from this population is: In a one-way ANOVA, we analyze only one Which of the following pairs of events are mutually exclusive For a one-tailed test, the p-value is What is the critical value of t for the hypothesis test In a hypothesis test, a Type II error occurs when A quantitative variable is the only type of variable that can You toss a coin nine times and observe 3 heads and 6 tails. This event is a In a hypothesis test, a Type I error occurs when What is the critical value of z for the hypothesis test A researcher wants to test if the mean annual salary of all lawyers in a city is different than $110,000. The null hypothesis for this example will be that the population mean is The mean of a discrete random variable is its For a goodness-of-fit test, the frequencies obtained from the performance of an experiment are the An error that occurs because of chance is called You randomly select two households and observe whether or not they own a telephone answering machine. Which of the following is a simple event To make tests of hypotheses about more than two population means, we use the The mean of a discrete random variable is the mean of its The alternative hypothesis is a claim about a If you divide the number of elements in a sample with a specific characteristic by the total number of elements in the sample, the dividend is the The regression model y = A + Bx + e is The regression model y = A + Bx is Which of the following assumptions is not required to use ANOVA

Round to the nearest whole number. E = 25.9, ? = 122.25, confidence level = 90%. Round to the nearest whole number. 4. True or False. a.The null hypothesis is a claim about a population parameter that is assumed to be false until it is declared false. True False b. An alternative hypothesis is a claim about a population parameter that will be true if the null hypothesis is false. True False c. The critical point(s) divide(s) is some of the area under a distribution curve into rejection and nonrejection regions. True False d. The significance level, denoted by ?, is the probability of making a Type II error, that is, the probability of rejecting the null hypothesis when it is actually true. True False e. The nonrejection region is the area to the right or left of the critical point where the null hypothesis is not rejected. True False 5. Fill in the blank.

Using data from the U.S. Census Bureau and other sources, www.nerdwallet.com estimated that considering only the households with credit card debts, the average credit card debt for U.S. house- holds was $15,523 in 2014 and $15,242 in 2013. Suppose that these estimates were based on random samples of 600 households with credit card debts in 2014 and 700 households with credit card debts in 2013. Suppose that the sample standard deviations for these two samples were $3870 and $3764, respectively. Assume that the standard deviations for the two populations are unknown but equal. Let ?1 and ?2 be the average credit card debts for all such households for the years 2014 and 2013, respectively. What is the point estimate of ?1 ? ?2? Round to two decimal places. Do not include the dollar sign. Construct a 98% confidence interval for ?1 ? ?2. Round to two decimal places. Do not include the dollar sign. What is the lower bound? Round to two decimal places. What is the upper bound? Round to two decimal places. Using a 1% significance level, can you conclude that the average credit card debt for such households was higher in 2014 than in 2013? Use both the p-value and the critical-value approaches to make this test. Reject Ho Do not reject Ho 10. Gamma Corporation is considering the installation of governors on cars driven by its sales staff. These devices would limit the car speeds to a preset level, which is expected to improve fuel economy. The company is planning to test several cars for fuel consumption without governors for 1 week. Then governors would be installed in the same cars, and fuel consumption will be monitored for another week. Gamma Corporation wants to estimate the mean difference in fuel consumption with a margin of error of estimate of 2 mpg with a 90% confidence level. Assume that the differences in fuel consumption are normally distributed and that previous studies suggest that an estimate of sd=3sd=3 mpg is reasonable. How many cars should be tested? (Note that the critical value of tt will depend on nn, so it will be necessary to use trial and error.)
