Answer
See Sample Calculation from 5-1.
a)
M = (p2 - 1)(p1-1) / (p2 - p1)
Peak 5 = p1 (highest)
Peak 6 = p2 (second highest)
M = (1789.2-1)(1590.6-1)/(1789.2-1590.6) = 14312.8
b)
p1 = (M + z)/z
1590.6 = (14312.8 + z) / z
z = 9.00
Work Step by Step
Formulas needed from Sample Calculation 5-1:
M = (p2 - 1)(p1-1) / (p2 - p1)
p1 = (M + z)/z
