Weatherwise magazine is published in association with the American Meteorological Society. Volume 46, Number 6 has a rating system to classify Nor'easter storms that frequently hit New England states and can cause much damage near the ocean coast. A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating.
(a) Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down or getting worse. What would be the null hypothesis regarding average wave height?
μ > 16.4
μ < 16.4
μ = 16.4
μ ≠ 16.4
(b) If you wanted to test the hypothesis that the storm is
getting worse, what would you use for the alternate
hypothesis?
μ < 16.4
μ > 16.4
μ ≠ 16.4
μ = 16.4
(c) If you wanted to test the hypothesis that the waves are
dying down, what would you use for the alternate
hypothesis?
μ < 16.4
μ = 16.4
μ ≠ 16.4
μ > 16.4
(d) Suppose you do not know if the storm is getting worse
or dying out. You just want to test the hypothesis that the average
wave height is different (either higher or lower) from the
severe storm class rating. What would you use for the alternate
hypothesis?
μ > 16.4
μ ≠ 16.4
μ < 16.4
μ = 16.4
(e) For each of the tests in parts (b), (c), and (d), would
the area corresponding to the P-value be on the left, on
the right, or on both sides of the mean?
right; left; both
both; left; right
left; right; both
left; both; right
a)
The null hypothesis is
H0: = 16.4
b)
The alternative hypothesis is
H1: > 16.4
c)
The alternative hypothesis is
H1: < 16.4
d)
The alternative hypothesis is
H1: 16.4
e)
'>' means right , '<' mean left , '' means both
Ans: Right ; Left ; Both

Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of μ = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers....

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating.

A random sample of 51 adult coyotes in a region of northern Minnesota showed the average age to be x = 2.03 years, with sample standard deviation s = 0.82 years. However, it is thought that the overall population mean age of coyotes is μ = 1.75. Do the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use α = 0.01. (a) What is the value of...
