As a part of your work for an environmental awareness group, you
want to test a claim that the mean waste generated by adults in the
United States is more than 4 pounds per day. in a random sample of
10 adults in the United States, you find the mean waste generated
per person per day is 4.54 pounds with a standard deviation of 1.21
pounds. at alpha=0.05, can you support the claim?
a) write the claim mathematically and identify H0 and Ha.
b) find the critical value(s) and identify the rejection
region(s).
c) find the standardized test statistic. If convenient, use
technology.
d) decide whether to reject or fail to reject the null
hypothesis.
e) interpret the decision in the context of the original
claim.
for each claim, assume the population is normally
distributed.
