Step-by-step explanation:
Given If the mean of the following frequency distribution is 6.4 then find the value of p
- So Mean = 6.4
- Class frequency x (f)(x)
- 1 – 3 3 2 6
- 3 – 5 p 4 4p
- 5 – 7 5 6 30
- 7 – 9 3 8 24
- 9 – 11 2 10 20
- 11 – 13 1 12 12
- 14 + p 92 + 4p
- Now Mean = x bar = 6.4
- So x bar = ∑ f1 x1 / ∑ f1
- 6.4 = 92 + 4p / 14 + p
- 6.4(14 + p) = 92 + 4p
- 89.6 + 6.4 p = 92 + 4p
- 6.4 p – 4p = 92 – 89.6
- 2.4 p = 2.4
- p = 2.4 / 2.4
- Or p = 1
