Use the normal approximation to find the indicated probability.
The sample size is n, the population proportion of
successes is p, and X is the number of successes
in the sample.
n = 85, p = 0.64: P(X >
52)
Solutions
Expert Solution
Using Normal Approximation,
n= 85, p= 0.64, q = 0.36
Mu = n*p = 54.4
Sigma = sqrt(n*p*q) = 4.4254

Section 8.1 #38
A sample of size n = 80 is drawn from a
normal population whose standard deviation is σ = 6.8.
The sample mean is x̄ = 40.41.
