The average annual precipitation for a large Midwest city is
30.85 inches with standard deviation of 3.6 inches. What is the
probability that a random selection of 49 years will have mean
precipitation higher than 30 inches?

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.

(b) Explain and show what test statistic you're using and how
to get the p-value

The standard deviation of the annual precipitations of a region
over a period of 100 years was 16 cm. During the last 15 years a
standard deviation of annual precipitations was computed as 10 cm.
Test the hypothesis that the precipitations in the region have
become less variable than in the past, using a significance level
of (a) 0.05 and (b) 0.01. Use chi-square distribution.
