- What is meant by the sample space of an experiment?2.a STATISTICAL INFERENCEUniversity admission officers believe that scores on the Scholastic Aptitude Test (SAT) are strongly related to academic performance. In other words, high school students who have higher SAT scores will have higher grade point averages in college. For years, officers have been using SAT scores to place college students in certain classes their freshmen year. Now the admissions director wants to know if this policy is effective. You draw a random sample of 200 college sophomores and compare their SAT scores to their grade point average for their freshmen year. You calculate a Pearson’s r for correlations and receive a value of .254 between the two variables. You also calculate the significance of your findings (using a computer) and receive a significance value (p-value) of .000.In a short paragraph, based on the results from the correlation, what will you tell the admissions director? Ensure that you mention the direction of the relationship, the strength of the relationship, and…
- The ANOVA procedure is a statistical approach for determining whether or not... the means of more than two populations are not equal the means of more than two samples are not equal the means of more than two populations are equal the means of more than two samples are equal None of the above are trueEric Roberts, Inc. is a company that specializes in tax-deferred investment opportunities for its clients. Recently, this company offered a payroll deduction investment program for the employees of a particular company. The company estimates that the employees are currently averaging $110 or less per month in tax-deferred investments. A sample of 80 employees will be used to test the company’s hypothesis about the current level of investment activity among the population of employees. Assume the employee monthly tax-deferred investment amounts have a standard deviation of $70 and that a 0.05 level of significance will be used in the hypothesis test. What is the probability of the Type II error if the actual mean employee monthly investment is $125?A fast-food company uses two management-training methods. Method 1 is a traditional method of training, and Method 2 is a new and innovative method. The company has just hired 31 new management trainees. 15 of the trainees are randomly selected and assigned to Method 1, and the remaining 16 trainees are assigned to Method 2. After three months of training, the management trainees take a standardized test. The test is designed to evaluate their performance and learning from the training. The sample mean score and sample standard deviation of the two methods are given below. Company management wants to determine whether the company should implement the new training method. What is the alternative hypothesis for this test? A) Ha: μ1 − μ2 = 0 B) Ha: μ1 = μ2 C) Ha: μ1 − μ2 < 0 D) Ha: μ1 − μ2 > 0

He is told by his supervisor to investigate the difference in the average number of sick days between blue collar workers and whitecollar workers. So he obtained a random sample of 9 blue collar workers and a random sample of 9 white collar workers. He records the results below.At 10% level of significance, is there sufficient evidence to indicate a difference in mean sick days between blue collar workers and white collar workers.Sampling error can be avoided Multiple Choice by eliminating nonresponses (e.g., older people). either by using an unbiased estimator or by eliminating nonresponses. by no method under the statistician’s control. by using an unbiased estimator.
- Dr. Megan Markle, a professor of women's studies, is interested in determining if stress affects the menstrual cycle. Ten women are randomly sampled for an experiment and randomly divided into two groups. One of the groups is subjected to high stress for two months while the other lives in a relatively stress-free environment. The professor measures the menstrual cycle (in days) of each woman during the second month. The following data are obtained. High Stress 20 23 18 19 22 Relatively Stress Free 26 31 25 26 30 a.
