Transcribed Image Text:A taxi company tests a random sample of 10 steel-belted radial tires of a certain brand and records the tread wear in kilometers, as shown below. 58,000 61,000 67,000 41,000 55,000 59,000 64,000 52,000 63,000 51,000 Note that the sample variance becomes c2 times its original value if each observation in the sample is multiplied by c and unchanged if a constant is added to or subtracted from each value in the sample. Use these facts to find the standard deviation of this set of data by first dividing each observation by 1000 and then subtracting 60. For the data set that results from dividing each observation by 1000 and then subtracting 60, the variance is (Round to three decimal places as needed.) Using the information provided in the problem statement, identify how this value can be used to find the standard deviation of the original set of data. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) OA. Add then find the square root OB. Add then square the result OC. Multiply by then square the result. OD. Multiply by then find the square root. The standard deviation of the data is s= (Round to the nearest whole number as needed.)
