University of Phoenix Material Sonya Cargill 11/12/12 Week Five Calculations Read the chase scenarios, and answer the accompanying questions. 1. Statistics students were asked to fill a one-cup measure with raisin bran, thusly tap the cup lightly on the counter three times to settle the contents. If necessary, they were instructed to add more raisin bran to bring 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 compute the connote, median, and mode. Is the distribution skewed to the left or to the right? Mean 34. 5, Mode 23,33,36, Median 33 The mean is greater than the median. therefore the distribution should be skewed to the right. Which is the best measure of central movement and why? Mean the selective information doesnt have any real outliers and is roughly symmetric. Calculate the monetary standard deviati on. Why is there variation in the routine of raisins in a cup of raisin bran? Why major power 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 size of it flakes or possibly the size of the raisins that may skew the numbers from being equal. 2. The following are monthly rents paid by 30 students who live off-campus. 730730730930700570 901030740620720670 560740650660850930 600620760690710500 730800820840720700 Find the mean, median, mode, and standard deviation. Mean 725 Mode 730 Median 720 Standard Deviation 114. 28 pick out the typical rent paid by a student. 720 Do the measures of central tendency agree? Explain. Yes, they are pretty close to each other (mean, mode, median) in range. Are there outliers or unusual data values? No Do you think the data could come from a normal population? Yes
