Should they start trying to do more surveys of Savannah tourists rather than rely on nationwide estimates?(Please give answer in form so I can understand it better to write response) You are the marketing manager at Visit Savannah, an organization committed to promotingtourism to Savannah, GA. Your boss, Sandy Beech, has sent you the following email:Marketing Manager,Promoting tourism starts by understanding our travelers. Previously, we've used nationalsurveys to approximate what travelers to Savannah are like. For example, a survey conducted bythe American Automobile Association (AAA) showed that nationwide a family of four spends anaverage of $215 per day while on vacation.But recently we've been concerned that these nationwide approximates do not accurately reflecttourism to Savannah. Thus, we recently conducted a survey of 100 families of four who traveledto Savannah, finding an average daily amount spent of $300. Based upon a similar survey donebefore for Savannah, we are assuming a population standard deviation of $51.I need your help to figure out whether spending by tourists to Savannah is different than thenationwide estimates reported by AAA.Specifically, I need you to develop a 95% confidence interval estimate of the mean amount spentper day by a family of four visiting Savannah. Based on the confidence interval you calculate,does itарреarthat the population mean amount spent per day by families visiting Savannahdiffers from the mean reported by the American Automobile Association (AAA)?Overall, should we start trying to do more surveys of Savannah tourists rather than rely onnationwide estimates?Thanks,Sandy Beech

From the given information, x¯=300σ=51n=100 95% confidence interval estimate of the mean amount…
