Question 266354: Can someone please help me with answering the following question?
As part of an advertising campaign, the Dairy Council is interested in determining the daily intake of milk among adults. A random sample of 10 adults gave the following results. (Values are given in ounces.)
23.0 30.6 20.3 10.1 11.5
21.8 22.2 26.9 21.0 30.1
a. Find x-bar and s for this data set.
b. Construct a 99 percent confidence interval for the mean daily intake of milk. You may assume the daily intake amounts are normally distributed. (Note: These results could then be used in later studies to see if the ad campaign is succeeding in increasing the amount of milk adults drink.) Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! As part of an advertising campaign, the Dairy Council is interested in determining the daily intake of milk among adults. A random sample of 10 adults gave the following results. (Values are given in ounces.)
23.0 30.6 20.3 10.1 11.5
21.8 22.2 26.9 21.0 30.1
a. Find x-bar and s for this data set.
xbar = 21.75 ; s = 6.8295
E = invT(0.995,9)*6.8295/sqrt(10) = 7.0186
----------------------------------------------------
b. Construct a 99 percent confidence interval for the mean daily intake of milk. You may assume the daily intake amounts are normally distributed.

99% CI: 21.75-7.0186 < u < 21.75+7.0186
