lecture(11.14): A professor offered a course that was offered half online and half in person. The professor hypothesized that students were spending less time on the material than on the off line material. At the end of the semester, students were asked to provide the amount of time they tended to course tasks during a week. The weeks were classified as online or in person, and the average amount of time is provided for 15 students.

man loves, as everyone should, to collect and analyze statistical information. He wishes to find a relationship between how many hours students study and how they do on their statistics tests. He takes a random sample of 16 students at Ideal U., asks how many hours they studied for a university-wide stat test and how they did on the test, enters the data into a computer for analysis and presents the results below. ANALYSIS OF HOURS AND GRADES (n = 16): Descriptive Statistics: HOURS GRADES Mean: 4.2 75.8 Mode: 5.0 79.0 St. Dev: 2.3 10.1 Quartiles: Q0 2.0 34.0 Q1 3.2 53.7 Q2 4.7 78.5 Q3 6.3 86.9 Q4 9.0 97.0 Regression Analysis: Reg.

DLP projectors are used in the majority of cinema projection systems and require a special light bulb to display a picture. Assume that the average life of a DLP bulb is 2,000 hours and that this failure time follows the exponential distribution. Answer the following questions, performing all computations with Excel functions.

Terri Vogel, an amateur motorcycle racer, averages 129.14 seconds per 2.5 mile lap (in a 7 lap race) with a standard deviation of 2.28 seconds . The distribution of her race times is normally distributed. We are interested in one of her randomly selected laps. (Source: log book of Terri Vogel) Let X be the number of seconds for a randomly selected lap. Round all answers to 4 decimal places where possible.b. Find the proportion of her laps that are completed between 131.08 and 134.03 seconds. ___________________c. The fastest 2% of laps are under seconds.____________________d. The middle 70% of her laps are from ____ seconds to ____ seconds.
The probability that a student passes an exam is 0.92, given that he studied. The probability that he passes the exam without studying is 0.15. As he is a diligent student, we know that the probability that the student studies for an exam is just 80%. Given the student passed the exam, determine the probability that he studied. Use a calculator to simplify your answer, and round it to three decimal places.

O An exponential model is appropriate because the residual plot does not show a clear pattern. O A inear model is appropriate because the scatterplot shows a strong, positive linear relationship. A power model is appropriate…
