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:

Answer:
1.25*10^-4
2*10^-4
3.25*10^-10
Step-by-step explanation:
Answer:
130
Step-by-step explanation:
Given the equation of the relation as c(h) =50 +20 h where c(h) is the total cost for h hours and h is the number of hours of use, then to find the cost of jet ski if 4 hours were used will be;
c(h)=50 +20 h
c(4)=50 +20*4
c(4)=50 +80
=130
