- At the auction of the music collection, there is 1 masterpiece sheet music whose composer is unknown. A professor from the College of Music, Universität der Künste Berlin was asked to analyze who the score composer is. You are asked to help analyze statistically. The professor saw there were 2 names who may have been the composer, namely: Johann Strauss II and Tchaikovsky. The the professor also provides general data, namely the average number of tones per bar of each composer. Give the results of your analysis, who is the composer of the sheet music. Calculations are made using a spreadsheet! Note: Take the last 3 digits of your ID (2602296545 ). Use the step below: 1. For example, for example ID 2602296545 → 545 is taken. 2. Replace number 5 with number 1; example: ID 545 → 145 3. Last 3 digits of your new ID == abc; example 145: a = 1, bc = 45.There is a lot of data that we could collect about individuals on a treadmill, like data on the type of exercise(walking, jogging, running), or data on how they exercise/20mi mins, 30 mins, hour). List three more examples of each type of data, and how the data would be measured.The authors of a paper randomly selected two samples of patients admitted to the hospital after suffering a stroke. One sample was selected from patients who received biofeedback weight training for 8 weeks, and the other sample was selected from patients who did not receive this training. At the end of 8 weeks, the time it took (in seconds) to stand from a sitting position and then to sit down again (called sit-stand-sit time) was measured for the people in each sample. Data consistent with summary quantities given in the paper are given below. For purposes of this exercise, you can assume that the samples are representative of the population of stroke patients who receive the biofeedback training and the population of stroke patients who do not receive this training.

- When the measure of spread is compared between two data sets, data set A has an interquartile range of 12, and data set B has an interquartile range of 23. How do the values of data set A compare to data set B? The values of data set A are about the same on average as the values of data set B. The values of data set A are more spread out compared to the values of data set B. The values of data set A are less spread out compared to the values of data set B. The values of data set A are less on average compared to the values of data set B.ep.com/modules/questions/qq.php?testid3547&assignment_id=43760216&strand=2816&element=D18882&totalQuestions3D10&ck=DUTNLZN6Y2F7HO8 Maps 2 3 4 5 6 7 8 9 10 Save Submit Charlie and Kyle are training for a track meet. Charlie's practice times for an event are represented on the graph, where y the total miles run and x = the number of hours.

Which statement BEST describes the rates of the runners? es 4) A) Kyle's rate is 1.5 miles per hour greater than Charlie's rate. B) Charlie's rate is 1 mile per hour greater than Kyle's rate. Kyle's rate is - mile per hour greater than Charlie's.

It recruited 1100 random women from the L.A. area and measured the length of their hair. They gave 500 women the new product in unmarked bottles to use over a 6-month period. The other 600 women received unmarked bottles with mostly water and fragrance to use over a 6-month period. None of the women knew which product they received. They found that 450 out of 500 women that received the new product showed hair growth of 1-2 inches. Only 90 out of 600 women that used the water/fragrance combination showed hair growth of 1-2 inches. Women who received the treatment are Blank %/ blank % = Blank times to show hair growth.Ginny’s professors conspired to all give a test on the same day. She gets an 82 on her psychology exam with μ = 76 and σ = 12. She receives a z-score of -.25 on her management exam. Finally, she scored at the 50th percentile on her normally distributed math exam. Place her test scores in order from lowest to highest score.
- 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. Here are data on distance and number of days until deaths began in each later group: Distance xx 2 5 4 4 4 6 Days yy 4 21 29 40 47 49 Use a calculator or software to find the following values. (a) Find the mean and standard deviation of xx. MEAN: STANDARD DEVIATION: (b) Find the mean and standard deviation of yy. MEAN: STANDARD DEVIATION: (c) Find the correlation rr between xx and yy. r:Several states have argued that the 65-mph speed limit has no justification and have refused to enforce it. The federal Department of Transportation (DOT) believes that the 65-mph limit saves lives. To illustrate its contention, the department regressed the number of traffic fatalities (Y) last year in a state on the state’s population (X1), the number of days of snow cover (X2), and the average speed of all cars (X3).

The following data represent pH levels in ground water for a random sample of 102 West Texas wells. A pH less than 7 is acidic and a pH above 7 is alkaline. Scanning the data, you can see that water in this region tends to be hard (alkaline). Too high a pH means the water is unusable or needs expensive treatment to make it usable†. These data are also available for download at the Companion Sites for this text. For convenience, the data are presented in increasing order.
