1. Consider the following two data sets. 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. Through visualization not mathematically determine the location of mean, median and mode classes from the given Histogram.
