Question 1. Thirty graduate students were asked how many credit hours they were taking in the current quarter. Download the available data: Calculate the mean, median, standard deviation, variance, and range for this sample using Excel. Write a sentence explaining what each measure means. What is the standard error of the mean based on the data? What would be the best point estimate for the population credit hours? (“Population” refers to all graduate students’ credit hours in the universe.) What...

A survey among freshmen at a certain university revealed that the number of hours spent studying the week before final exams was normally distributed with mean 26 and standard deviation 5. Use the TI-84 PLUS calculator to answer the following. Round the answer to at least four decimal places. (a) What proportion of students studied more than 36 hours? (b) What is the probability that a randomly selected student spent between 13 and 32 hours studying? (c) What proportion of...

A survey of 704 randomly selected students was conducted to determine student opinion about taking full- semester classes, 12-week classes, or eight-week classes. The survey reported that 25% of the students surveyed preferred 12-week sections. The survey estimate had a margin of error of 2 percentage points. A margin of error is reported because The people doing the survey may have recorded results incorrectly. Students may intentionally respond incorrectly. Students may misunderstand the survey questions. Sample proportions vary from sample...

Instructions: Read the scenario and answer the questions below. Round all probabilities and proportions to 4 decimal places. The Graduate Record Examination (GRE) is a test required for admission to many U.S. graduate schools. Students' scores on the quantitative portion of the GRE follow a normal distribution with mean 150 and standard deviation 8.8. (Source:www.ets.org). A graduate school requires that students score above 160 to be admitted. 1. What proportion of combined GRE scores can be expected to be over...
