Discuss a population standard deviation


Discuss the below:

Q: A fast food franchiser is considering building a restaurant at a certain location. Based on financial analyses, a site is acceptable only if the number of pedestrian passing the location averages more than 100 per hour. The number of pedestrians observed for each of 40 hours was recorded and stored in the attached excel file . Assuming that the population standard deviation is known to be 12, can we conclude that the site is acceptable? (set your own significance level)
