Using the Central Limit Theorem, the standard error for the distribution of 559 restaurants is given by:
s = 0.0398.
<h3>What does the Central Limit Theorem state?</h3>
The Central Limit Theorem states that for a population with standard deviation and sample size n, the standard error is given by:
For this problem, the parameters are given as follows:
Hence:
s = 2.94/sqrt(559) = 0.0398.

A suitable probability calculator will tell you that probabilty is about 25.9%.
_____
The normalcdf function on this calculator gives an area between a lower and upper limit. If the upper limit is more than about 8 standard deviations above the mean, the 10th decimal place is unaffected. Since the standard deviation here is about 5, we need to have an upper limit that is about 40 above the mean of about 30. We have chosen 80 as a nice round number and to give a little more margin.
