The Department of Inland Fisheries and Game did a survey of ice fishing shacks last winter. A random sample of 195 shacks on the Kennebec River found that 152 had some type of heat source. On the Eastern River, a sample of 162 shacks found that 118 had some type of heat.
a. what are the null and alternative hypotheses?
b. At alpha = 0.05 does this indicate that the proportions are different on the two rivers?
c. How does this compare with the result in #3?

The Fisheries did a survey of ice fishing shacks last winter. A random sample of 195 shacks on the Salmnac River found that 152 had some type of heat source. On the Thomas River, a sample of 162 shacks found that 118 had some type of heat. A) Find a 99% confidence interval for p1 -- p2. B) Based upon these samples, can we determine that the populations on the Salmnac River and on the Thomas River are different? C)...
