Expert Solution
Step 1

Given Information:

Sample size (n) = 100

X = 59

Hypothesized value of population proportion is p0=0.50

To test whether the proportion of customers who visit the site and make a purchase is different than 50%.

 

Population parameter is the Population proportion p.

Conditions required for using a z-distribution are: np10 and n1-p10

That is:

np=1000.50=50>10

n1-p=1001-0.50=5010

Thus, the two conditions are met.
