University of Phoenix Material Sonya Cargill 11/12/12 Week Five Calculations Read the following scenarios, and answer the accompanying questions. 1. Statistics students were asked to drive a one-cup measure with raisin bran, then tap the cup lightly on the counter three times to settle the contents. If necessary, they were instructed to add more raisin bran to submit the contents exactly to the one-cup line, then spread the contents on a large plate, and count the raisins.The 13 students who chose Kelloggs Raisin Bran obtained the results shown below 23334436294231336136342324 front the mean, median, and mode. Is the dissemination skewed to the left or to the right? recall 34. 5, Mode 23,33,36, median(prenominal) 33 The mean is greater than the median. therefore the distribution should be skewed to the right. Which is the best measure of central tendency and why? Mean the data doesnt have any real outliers and is roughly symmetric. Calculate the standard deviation. Why is t here variation in the piece of raisins in a cup of raisin bran? Why might it be difficult for Kelloggs to reduce variation? Standard deviation is 10. 3087.The variation in the number of raisins in a cup of raisin bran could be a result the coat flakes or possibly the size of the raisins that may skew the numbers from world equal. 2. The following are monthly rents paid by 30 students who lie with off-campus. 730730730930700570 901030740620720670 560740650660850930 600620760690710500 730800820840720700 Find the mean, median, mode, and standard deviation. Mean 725 Mode 730 Median 720 Standard conflict 114. 28 Describe the typical rent paid by a student. 720 Do the measures of central tendency agree? Explain. Yes, they are pretty most to each other (mean, mode, median) in range. Are there outliers or singular data values? No Do you think the data could incur from a normal population? Yes
