Homework SourseUse the following table Value Frequency 27 7 31 6 7 32 27 7
| Use the following table: |
| Value | Frequency |
| 27 | 7 |
| 31 | 6 |
| 7 | 32 |
| 27 | 7 |
| Find the weighted mean. (Round your answer to the nearest tenth.) |
| Use the following table: |
Solution
Value(x) ---- frequency (f) ----- f*x
27------- 7 -----189
31 ------- 6----- 186
7 ------- 32 ----- 224
27 ------ 7 ----- 189
sumf = 52 ---- sum(f*x) = 788
Mean = sum(f*x)/sum(f) = 788/52 = 15.15
