Over a 18 day period, daily measurements of silver yield from
a mine us taken. The company has an original goal of the 60th
percentile being more than 50 tons. From the 18 days, 8 days
yielded less than 50 tons. No day yielded exactly 50 tons. Test to
see if the company’s goal is upheld.
(a) State the hypothesis for testing this claim.
(b) Explain and show what test statistic you're using and how
to get the p-value
(c) Give your conclusion. Explain.
Solutions
Expert Solution
Let p denotes the true proportion of daily measurements yielding less than or equal to 50 tons.

(NO MINI TAB)
Six measurements are taken of the thickness of a piece of
18-guage sheet metal. The measurements (in mm) are: 1.316, 1.308,
1.321, 1.303, 1.311, 1.310
Make a boxplot of the six values.
Should the t distribution be used to find 99%
confidence interval for the thickness? If so, find the confidence
interval. If not explain, why not.
Six independent measurements are taken of the thickness of
another piece of sheet metal. The measurements this time are:
1.317,...

You are a a silver retailer. You source silver from all over the
world and you sell it to your clients. Your main clients are
battery manufacturers and circuit manufacturers. Today (July 4th)
you buy 10,000 oz of silver at 16 dollars an ounce for your
inventories.
If you want to hedge your spot position in the futures market,
would you go long or short?
Suppose you expect to sell all this silver over the next six months
so you...
