Problem 68E
For the binomial sample sizes and null hypothesized values of p in each part, determine whether the sample size is large enough to use the normal approximation methodology presented in this section to conduct a test of the null hypothesis H0: p = p0.
ANSWER:
Solution
We have to determine whether the sample size is large enough to use the normal approximation
For the following
If , the sample size is large enough to use normal approximation
Step 1 of 5
a)
=1-0.975=0.025
Then =900(0.975)
=877.5>15
And =900(0.025)
=22.5>15
Here
Hence the sample size is large enough
