Answer:
The confidence interval for the true mean calorie content is
Step-by-step explanation:
In this problem we know the mean and standard deviation fo the sample, so we can compute the CI like this:
We need to determine t for 10-1=9 degrees of freedom and 99% confidence level. We look up in the t-table and the value for t is 3.2498.
Then we can calculate the limits of the CI:
Multiplicity is how many times each root repeats
(x-r1) where r1 is the root
root is 1 of multiplicity 2 means
(x-1)^2
root -2 multiplicity 3 means
(x+2)^3
so the function is
(x-1)^2(x+2)^3
f(x)=(x-1)^2(x+2)^3
expanded
f(x)=
(x-1)^2(x+2)^3
(x-r1) where r1 is the root
root is 1 of multiplicity 2 means
(x-1)^2
root -2 multiplicity 3 means
(x+2)^3
so the function is
(x-1)^2(x+2)^3
f(x)=(x-1)^2(x+2)^3
expanded
f(x)=
(x-1)^2(x+2)^3
