Same with this one I can't get the critical value or test statistic.  Should I reject the null?

Expert Solution
Step 1

Given information-

We have given two population samples.

Let,

p1 = proportion of first population sample

p2 = proportion of second population sample

For first population-

n1 = 327

x1 = 229

For second population-

n2 = 415

x2 = 246

Population proportion of first population-

Statistics homework question answer, step 1, image 1

The Population proportion of second population-

Statistics homework question answer, step 1, image 2

 

Given Hypothesis is-

Null Hypothesis, H0: p1 = p2

Alternate Hypothesis, Ha: p1 > p2

Significance level, α = 0.002

Step 2
