Small Mean Problem. Grandfather clocks have a particular
market in auctions. You are given a random sample of 21 purchases
of grandfather clocks at auctions in Pennsylvania. The sample
statistics are:
Mean = $1,343.04
Std Dev = $414.04
C.V. = 30.83
N = 21
You are asked to create a 90% Confidence Interval around the
price for this sample.
The Lower Value for this confidence interval is? I just want
the answer. Use 3 decimal places for your answer and...
