If n(B) = 275, n(A ∩ B ∩ C) = 65, n(A ∩ B ∩ CC) = 50, and n(AC ∩ B ∩ C) = 145, what is n(AC ∩ B ∩ CC)?

If n(A) = 45, n(B) = 18, and n(A ∩ B) = 7, find n(A ∪ B).

If  n(A) = 69, n(B) = 23, and n(A ∩ B) = 3, find n(A ∪ B).

If SSbetween =30, SSwithin=40, dfbetween=3, and dfwithin=20, than F=?

(a + b) (a+b+c) = a² + 2ab + b² + ac + bc Select one: O True O False

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.

If n(A) = 46, n(B) = 21, and n(A ∩ B) = 6, find n(A ∪ B).

If n(B) = 24, n(A ∩ B) =5, and n(A ∪ B) = 42, find n(A). 24 23 25 21

If n(A) = 40, n(B) = 24, and n(A ∩ B) = 1, find n(A ∪ B).
