Stoaches are fictional creatures with distinctive octarine stripes. Unfortunately they are vulnerable to the chirax virus (which isn’t actually harmful, but causes them great embarrassment).
In the general population of stoaches worldwide, 24% of stoaches carry the chirax virus. The local habitat has recently been devastated with both fires and floods. A researcher would like to know whether this has affected the local population’s health, and in particular, its rate of chirax infection.
A sample of 87 local stoaches is tested for chirax, and 26 of them have this humiliating condition. The researcher does a ?
z
-test to see whether the local chirax rate has changed.
Determine the ?
p
-value from this test. (Give your answer to 4 decimal places.)
Problem 2:
Twelve cars were equipped with radial tires and driven over a test course. Then the same 12 cars (with the same drivers) were equipped with regular belted tires and driven over the same course. After each run, the cars’ gas economy (in km/l) was measured. Is there evidence that radial tires produce better fuel economy?
