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:
Consider, pls, this solution:
If given a equation:
-12x²+11x-3=0, then
12x²-11x+3=0
D=b²-4ac=121-12*12=-23<0
