A^2 + b^2 = c^2...where a and b r the legs and c is the hypotenuse
35^2 + b^2 = 37^2
1225 + b^2 = 1369
b^2 = 1369 - 1225
b^2 = 144...by taking the sqrt of both sides, this eliminates the ^2 on left
b = sqrt 144
b = 12...so ur other leg is 12 <==

Answer:
Kindly check explanation
Step-by-step explanation:
To construct confidence interval for difference in proportion ; the following conditions must be met :
1.) The selected samples must have been randomly chosen or selected from a larger population. This is essential in other to eliminate bias.
Each group of samples must be independently chosen. That is, the samples of bug customers chosen must be independent of the sample of small customers selected.
The population from which the samples are drawn must be considerably larger than the sample size. Sample size, n should be ≤ 10% of the population size.
p1 = 160 / 200 = 0.8 ; (1 - p1) = 0.2
p2 = 120 / 300 = 0.4 ; (1 - p2) = 0.6
(p1 - p2) ± Zcritical * sqrt[(p1(1 - p1) /n1) + (p2(1 - p2) / n2)]
