Question: Using the same sample data from Problem #5 (56 out of 200 scanned computers actually had Norton antivirus software programs installed), perform a One-Proportion zInterval

Using the same sample data from Problem #5 (56 out of 200 scanned computers actually had Norton antivirus software programs installed), perform a One-Proportion zInterval Procedure to determine the 95% confidence interval for the population proportion, p, of computers that actually have Norton antivirus software programs installed.(Note: x = 56 and n = 200)

a.Determine whether both assumptions are met:

Assumption 1:Simple random sample?

Assumption 2:Both np and nq are 10 or greater

Are both assumptions met?

Even if you do not think the assumptions are met, please proceed with the following steps for the One Proportion z-Interval Procedure for a population proportion.

b.Step 1For a confidence level of 1 - , find z_/2

c.Step 2Find the confidence interval for the population proportion.

d.Step 3Interpret the confidence interval
