Answer:
Using the frequency distribution, I found the mean height to be 70.2903 with a standard deviation of 3.5795
Step-by-step explanation:
Given
See attachment for class
Solving (a): Fill the midpoint of each class.
Midpoint (M) is calculated as:
Where
Lower class interval
Upper class interval
So, we have:
Class 63-65:
Class 66 - 68:
When the computation is completed, the frequency distribution will be:
Solving (b): Mean and standard deviation using 1-VarStats
Using 1-VarStats, the solution is:
<em>See attachment for result of 1-VarStats</em>
Answer:
The expression which denotes the differences of squares is
n² - 225
As here 225 is a square of 15.

The x-intercepts of a function are used to express the function into factored form:
From (1/2, 0)
(x - 1/2)
From (6, 0)
(x-6)
(x - 1/2) (x-6) = 0
(2x -1)(x-6) = 0
The function is:
B. g(x) = (x – 6)(2x – 1)
