Answer:
Step-by-step explanation:
Y = 3x + 16 - 27
= x = 27 + 16 -3=40as
The 99% confidence interval for the true mean is given by:

where:

is the sample mean = 69.7

is the standard deviation = 2.8

is the test statistics = 2.58 for for 99% confidentce interval.
n is the sample size = 772.
Therefore, the 99% confidence interval is:
From my understanding your asking what 20% of $48 is.
in that case it would be $9.60
