Answer:
16
Step-by-step explanation:
Make a proportion:
66/12 = (104-r)/r
Simplify:
r = 16
Since there were 6 slices, and he ate 1/3, 6*1/3= 2, so he ate 2 slices
Answer:
40 minutes
Step-by-step explanation:
2/3 x 60 = 40
Answer:
The 99% confidence interval for the mean peak power after training is [299.4, 330.6]

Step-by-step explanation:
We have to construct a 99% confidence interval for the mean.
A sample of n=7 males is taken. We know the sample mean = 315 watts and the sample standard deviation = 16 watts.
For a 99% confidence interval, the value of z is z=2.58.
We can calculate the confidence interval as:

The 99% confidence interval for the mean peak power after training is [299.4, 330.6]
