Again it is related to my trip to Vancouver: Fly to Vancouver and to have a vacation is not a cheap trip. I would like to know the average USD amount two people (a couple) spend, the total amount, including Airfares, Hotel, Car Rental, Meals, and all other expenses. So again, I randomly ask n 93 couples of tourists in the Airport: how much money each couple spent in the whole trip since they, like us, are ready to fly back home. I then put each individual couple's $ amount into my Excel sheet in one column. I actually calculated the sample mean = 2,873 and sample Standard Deviation = 222, assume I want a 95% confidence interval. Tell me the lower confidence level with 2 decimals (Dollar amount), ex. if the answer is $1256.786, write 1256.79. Tip: Use the template you created following my video.
