Question

Lucy wants to make a confidence interval to estimate the true mean wait time explain throughly why Lucy has or has not satisfied the normal condition for contstructing a confidence interval

Answer 1

The confidence interval would help Lucy determine the probability that a parameter will fall between two values around the mean.

How to determine the normal condition for the confidence interval?

The question is incomplete, as the needed parameters to answer the question are missing.

So, I will list the normal conditions for constructing the confidence interval

The condition for constructing the confidence interval include:

• The sample must be a random sample
• The variables must be independence
• The samples must be a large sample i.e. 30 or greater
• The sample size should be less than or equal to 10% of the population size
