Two samples are taken with the following numbers of successes and sample sizes
r1r1 = 38 r2r2 = 39
n1n1 = 86 n2n2 = 63

Find a 97% confidence interval, round answers to the nearest thousandth.

Expert Solution

We have given,

r1=38
n1=86

r2=39
n2=63

Level of significance =   0.03
Z critical value (by using Z table)=2.17
Estimate for sample proportion 1

Estimate for sample proportion 2

Confidence interval formula is

=(-0.3535, -0.0007)


Lower limit for confidence interval=-0.354

Upper limit for confidence interval is=-0.001
