Expert Solution

Step 1

Since you have posted a question with multiple sub-parts, we will solve first three sub-parts for you. To get remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.

b)
Here,

Class Interval	Frequency, f	Midpoint, x	fx
1.85-1.95	2	1.9	3.8
1.95-2.05	1	2	2
2.05-2.15	2	2.1	4.2
2.15-2.25	3	2.2	6.6
2.25-2.35	5	2.3	11.5
2.35-2.45	10	2.4	24
2.45-2.55	4	2.5	10
2.55-2.65	3	2.6	7.8
2.65-2.75	1	2.7	2.7
Total	31		72.6

Then, the mean is
$\begin{array}{rcl} M e a n & = & \frac{\sum_{}^{} f x}{\sum_{}^{} f} \\ = & \frac{72.6}{31} \\ = & 2.3419 \end{array}$
