Approximately 1718 have a score within that range.
We calculate the z-score for each end of this spectrum:
z = (X-μ)/σ = (2.5-3.1)/0.3 = -0.6/0.3 = -2
Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this z-score is 0.0228.
For the upper end:
z = (3.7-3.1)/0.3 = 0.6/0.3 = 2
Using a z-table, we see that the area to the left of, less than, this z-score is 0.9772.
The probability between these is given by subtracting these:
0.9772 - 0.0228 = 0.9544.
This means the proportion of people that should fall between these is 0.9544:
0.9544*1800 = 1717.92 ≈ 1718

Answer:
17 inches taller
Step-by-step explanation:
Way #1:
Megan is 5 ft 4 in = 4ft 16in
Sister is 3 ft 11 in
4-3=1ft
16-11=5 in
1 ft 5 in = 17 in
Way #2:
Megan is 5 ft 4 in = 64 in
Sister is 3 ft 11 = 47 in
64 in - 47 in
= 17 in
the line in slope intersect form has two types of information:
- how steep it is
- the height of the line
