Let us suppose we have data on the absorbency of paper towels that were produced by two different manufacturing processes. From process 1, the sample size was 10 and had a mean and standard deviation of 180 and 15, respectively. From process 2, the sample size was 4 with a mean and standard deviation of 360 and 50, respectively.

Question
Let us suppose we have data on the
absorbency of paper towels that were
produced by two different manufacturing
processes. From process 1, the sample size was
10 and had a mean and standard deviation of
180 and 15, respectively. From process 2, the
sample size was 4 with a mean and standard
deviation of 360 and 50, respectively.
X Your answer is incorrect.
Find a 95% confidence interval on the
difference in the towels' mean absorbency
produced by the two processes. Assume
the standard deviations are estimated
from the data.
Round your answers to two decimal places
(e.g. 98.76).
