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...

Small Mean Problem. Grandfather clocks have a particular market in auctions. One theory about the price at an auction is that it is higher when there are 10 or more bidders. From published data, the average price of all grandfather clocks is given as $1,327. You are not given a standard deviation for all clocks. You are given a random sample of 14 purchases of grandfather clocks at auctions in Pennsylvania where there are 10 or more bidders. Assume your...
