390 U.S.​ households,153 say they own a dog. At α=0.03​, is
there enough evidence to support the​ society’s 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.​ (d) Decide
whether to reject or fail to reject the null​hypothesis, and​ (e)
interpret the decision in the context of the original claim.
