Carmen attends a fashion institute that has no on-campus housing. The distance she commutes between her home and the campus is 19 kilometers. The meandistance commuted to campus among all students at the fashion institute is 15 kilometers with a standard deviation of 6 kilometers.(a) Find the -score of Carmen's commute distance relative to the commute distances among all the students at theinstitute. Round your answer to two decimal places.==(b) Fill in the blanks to interpret the -score of Carmen's commute distance. Make sure to express your answer in terms ofa positive number of standard deviations.Carmen's commute distance is standard deviations (Choose one) the mean commute distanceamong all students at the institute.X Ahmad has a popular blog about cooking and nutrition and regularly posts articles and videos. He has collected data about the length of time that viewers spentwatching two of his recent videos. For each video, he recorded the amount of time (in minutes) that each of 102 viewers spent watching it. The histogramsbelow show the distributions of the two data sets. Each histogram shows time (in minutes) on the horizontal axis and the number of viewers on the vertical axis.The means and standard deviations for the data sets are also given.Video 125-20+15+10+5+19.5 24.5 29.5 34.5 39.5 44.5 49.5 54.5 59.5 64.5 69.5Video 1 mean: 52.05 minutesVideo 1 standard deviation: 12.54 minutes20+15+10+5-Video 2+₂19.5 24.5 29.5 34.5 39.5 44.5 49.5 54.5 59.5 64.5 69.5(a) Identify the data set for which it is appropriate to use the Empirical Rule.Video 2 mean: 44.25 minutesVideo 2 standard deviation: 8.16 minutesAhmad wants to use the Empirical Rule to make some approximations about both data sets.

Janet is studying the relationship between the average number of minutes spent exercising per day and math test scores and has collected the data shown in the table. The line of best fit for the data is yˆ=0.46x+66.4. Minutes 15,20,25,30 Test Score 73,76,78, 80 (a) According to the line of best fit, the predicted test score for someone who spent 23 minutes exercising is 76.98.

An outbreak of the deadly Ebola virus in 2002 and 2003 killed 91 of the 95 gorillas in 7 home ranges in the Congo. To study the spread of the virus, measure " distance" by the number of home ranges separating a group of gorillas from the first group infected.

Solve the problem. A math teacher gives two different tests to measure students' aptitude for math. Scores on the first test are normally distributed with a mean of 22 and a standard deviation of 5. Scores on the second test are normally distributed with a mean of 71 and a standard deviation of 10.3. Assume that the two tests use different scales to measure the same aptitude. If a student scores 29 on the first test, what would be his equivalent score on the second test? (That is, find the score that would put him in the same percentile.) 078 83 86 85
To get a grade of C+, a student must have a mean average of 77 or greater. Jim has a mean average of 76 for 10 quizzes. He approaches his teacher and asks for a C+, reasoning that he missed a C+ by only one point. What is wrong with Jim's reasoning?
The accompanying table shows the height and weight of five football players in training camp. The body mass index (BMI) is used to assess the relative amount of fat in a person's body. If w is weight in pounds and h is height in inches, then BMI = 703wh. Some physicians consider your body fat abnormal if your BMI satisfies BMI-23>3. Which of the five players does not have abnormal body fat? does not have abnormal body fat. Player D Player B Player C Player E Player A ..
