### Exploring Data Deviations#### Problem Statement:A group of data items and their mean are given:- Data: 15, 25, 35, 60, 90, 135- Mean: 60Tasks:a. Find the deviation from the mean for each of the data items. b. Find the sum of the deviations from part (a).---#### Step-by-Step Instructions:**a. Calculate the Deviation:**For each data item, the deviation from the mean is calculated as follows:- Deviation = Data Item - Mean**b. Sum of Deviations:**Calculate the sum of all the deviations obtained in part (a).---#### Interactive Exercise:**a. Type the deviation from the mean for each of the data items.**| 15 | 25 | 35 | 60 | 90 | 135 ||-----|-----|-----|-----|-----|-----|| [ ] | [ ] | [ ] | [ ] | [ ] | [ ] |**b. The sum of the deviations in part (a) is**| [ ] |
