What will happen to the mean if the outlier is removed? 4, 5, 5, 7, 9, 17 1. it will not change. 2. it will be the same as the median. 3. it will decrease. 4. it will increase.

Solution:

The outlier is 17

With Outlier

4 + 5 + 5 + 7 + 9 + 17 = 47

47 / 6 = 7.83333333...

Without Outlier

4 + 5 + 5 + 7 + 9 = 30

30 / 5 = 6

Mean With Outlier - 7.8333...

Mean Without Outlier - 6

Answer - 3. It will decrease

17

Step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
