Answer 1

I can't see the histogram from what you pasted. I can compute the mean for you if you either (a) upload the histogram image or (b) list the frequency at each weight (115, 120, 125, …, 170).

How to compute the mean from the histogram
1. Read the frequency f_i for each weight value w_i (w_i = 115, 120, 125, …, 170).
2. Compute the sum of weighted values: S = Σ (w_i × f_i).
3. Divide by the total number of students (36): mean = S / 36.

Example format you can give me:
115: 2
120: 1
125: 3
…
170: 0

If you give the frequencies I will compute the mean for you.
