An educational researcher decided to predict the college GPA of entering students based on their high school GPA and the number of books they have read in the past year. Interpret the residual for a student with a College GPA equal to 3.00, a high school (HS) GPA equal to 2.87 and who has read 16 books in the past year. College GPA = 1.07 + 0.178(HS) GPA+1.05 books a) The student performed better than expected. b) The student performed exactly as expected. c) The student performed worse than expected. d) Cannot be determined from the given information.
Approximately 1.65 million high school students take the Scholastic Aptitude Test (SAT) each year, and nearly 80 percent of the college and universities without open admissions policies use SAT scores in making admission decisions. The current version of the SAT includes three parts: reading comprehension, mathematics, and writing. A perfect combined score for all three parts is 2400. A sample of SAT scores for the combined three-part SAT are as follows: a. Show a frequency distribution and histogram. Begin with the first bin starting at 800, and use a bin width of 200. b. Comment on the shape of the distribution. c. What other observations can be made about the SAT scores based on the tabular and graphical summaries?
In a sampling application to determine the average weight of students enrolled in a fitnessclass, if the sample estimate is 120 pounds, the precision is 10 pounds, and the reliability is90 percent, which of the following statements is true?a. There is 10 percent likelihood that the average weight of a student in the class is morethan 130 pounds.b. There is 10 percent likelihood that the average weight of a student in the class is less than110 pounds.c. There is 90 percent likelihood that the average weight of a student in the class is less than110 pounds or more than 130 pounds.d. There is a 90 percent likelihood that the average weight of a student in the class is between110 and 130 pounds.
The mean height of women in a country (ages 20−29) is 63.9 inches. A random sample of 60 women in this age group is selected. What is the probability that the mean height for the sample is greater than 65 inches? Assume σ=2.84. The probability that the mean height for the sample is greater than 65 inches is nothing.
In the 1970s, one million college-bound students were surveyed and asked to compare themselves to their peers. Some of the key findings of the survey were as follows: a. 70% of the students rated themselves as above average in leadership ability, while only 2% rated themselves as below average in this regard. b. With respect to athletic skills, 60% of the students rated their skills as above the median and only 6% of students rated themselves as below the median. c. 60% of the students rated themselves in the top 10% in terms of their ability to get along with others, while 25% of the students felt that they were in the top 1% in terms of this interpersonal skill. Required: What type of cognitive bias reveals itself in the data mentioned above? How might this cognitive bias adversely influence a manager’s planning, controlling, and decision-making activities? What steps could managers take to reduce the possibility that this cognitive bias would adversely influence their actions?
The Economic Policy Institute periodically issues reports on wages of entry-level workers. The institute reported that entry-level wages for male college graduates were $21.68 per hour and for female college graduates were $18.80 per hour in 2011. Assume that the standard deviation for male graduates is $2.30, and for female graduates it is $2.05. What is the sampling distribution of for a random sample of 50 male college graduates? What is the sampling distribution of for a random sample of 50 female college graduates? In which of the preceding two cases, part (a) or part (b), is the standard error of smaller? Why?

For the year 2010, 33% of taxpayers with adjusted gross incomes between $30,000 and $60,000 itemized deductions on their federal income tax return. The mean amount of deductions for this population of taxpayers was $16,642. Assume that the standard deviation is σ = $2,280. If required, round your answer to two decimal places. (a) What are the sampling distributions of x for itemized deductions for this population of taxpayers for each of the following sample sizes: 30, 50, 100, and 400?

In this chapter we showed how a simple random sample of 30 EAI employees can be used to develop point estimates of the population mean annual salary, the population standard deviation for annual salary, and the population proportion having completed the management training program. a. Use Excel to select a simple random sample of 50 EAI employees. b. Develop a point estimate of the mean annual salary. c. Develop a point estimate of the population standard deviation for annual salary. d. Develop a point estimate of the population proportion having completed the management training program.
