Data Set I 12 25 37 41 Data Set II 19 32 44 15 48 Notice that each value of the second data set is obtained by adding 7 to the corresponding value of the first data set. The mean and standard deviation for Data Set I is 24.6 and 14.6389 respectively. Then the mean and variance for Data Set II is equal to a. Mean = 24.6 and Variance = 214.3 b. Mean = 31.6 and Variance = 14.6389 c. Mean = 31.6 and Variance = 214.3 d. Mean = 24.6 and Variance = 14.6389 2. If the coefficient of variation for prices is 5.483% and the variance price Rs? 0.7225 then mean is equal to a. 1.3177 b. 15.5 c. 7.5889 d. 0.5483 3.
