Decide whether the normal sampling distribution can be used. If it can be​ used, test the claim about the difference between two population proportions

p 1p1

and

p 2p2

at the given level of significance

alphaα

using the given sample statistics. Assume the sample statistics are from independent random samples.

​Claim:

p 1p1equals=p 2p2​,

alphaαequals=0.010.01

Sample​ statistics:

x 1x1equals=2323​,

n 1n1equals=113113

and

x 2x2equals=103103​,

n 2n2equals=179179

a) find the standardized test statistics
