Hi!
Lets call X to the consumption of milk per week among males over age 32. X has a normal distribution with mean μ and standard deviation σ.
When you know the population standard deviation σ of X , and the sample mean is 
, the variable q has distribution N(0,1):
Then you have:
This defines a C - level confidence interval. For each C the value of k is well known. In this case C = 0.98, then k = 2.326
Then the confidence interval is:
Answer:
The answer is 35
Step-by-step explanation: Dividing the first fraction into lowest terms makes the problem easier to solve.

Answer:
Q= 126°
Step-by-step explanation:
Using the picture given, because these are parallel lines broken by a transversal, we can say the following
M=A=Q=F
B=C=D=G
Since, for example, M and C are the same line, we can say that M+C=180 and so on.
M=Q
Q= 126°
