Answer 1

Please find attached the figure with the complete question including the histogram

Answer:

$\large\boxed{\large\boxed{20members}}$

Explanation:

You must understand the histogram.

The horizontal axis shows the weights in pounds measured using the central points of the intervals. The intervals are supposed to be [105,115], [115,125], [125,130], . . .

The height of the bars represents the frequencies or number of members for each interval. You can read the height of each bar on the vertical axis.

Thus, you find the number of members for each interval:

• first interval:                   5 members
• second interval:             4 members
• third interval:                  2 members
• fourth interval (blank):   0 members
• fifth interval:                   5 members
• sixth interval (blank):     0 members
• seventh interval:            4 members

Total: 5 + 4 + 2 + 0 + 5 + 0 + 4 = 20 members ← answer
