Question 1056586: An article in the San Jose Mercury News stated that students in the California state university system take 4.5 years, on
average, to finish their undergraduate degrees. Suppose you believe that the mean time is longer. You conduct a survey of
49 students and obtain a sample mean of 5.1 with a sample standard deviation of 1.2. Do the data support your claim at the
1% level?

Question 1066211: Use U = {1,2,3,4,5,6,7,8,9,10} , A={1,4,5} , B={5,6,8,9} and C = {1,5,6} to find the given set.(AUB)∩C
--- So far I have AuB = 1,4,5,6,8,9 and ∩C = 1,5,6 so it is 4,8,9 left but I am unsure of where to go from there?

Question 1073522: Another operation that can be defined on sets A and B is the difference of the sets, denoted by
A − B.
Here is the formal definition of the difference of sets A and B.
A − B = {x | x is in A and x not in B}
Thus
A − B
is the set of elements that belong to A but not to B. For instance, let
A = {1, 2, 3, 7, 8}
and
B = {2, 7, 11}.
Then
A − B = {1, 3, 8}.
Determine the difference, given that
U = {1, 2, 3, 4, 5, 6, 7, 8, 9},
A = {2, 4, 6, 8},
and
B = {1, 6, 8, 9}.
