2. A hypothesis test is performed in a study of American households to learn about the proportion of them
that have four dogs; the null and alternative hypotheses are stated below. Address (a) – (f).
H: p=0.13
H¸:p<0.13
(a) The researchers determined that 39 of the 500 randomly selected sample American households
had four dogs. After verifying that all the conditions necessary for the statistical inference
associated with this hypothesis test -- Randomization, Independence, 10% Condition, and
Sufficiently Large Sample Size (a.k.a. At Least 10 Successes and 10 Failures) – are satisfied,
the researchers correctly compute the P-Value; it is approximately 2.7269 e – 4 or 2.7269×10*.
Use the appropriate symbols and values to communicate the specific conditional probability that
the P-Value represents in the context of this particular study.
(b) Write a sentence, or two, carefully describing the specific event in the context of this particular
study which has probability equal to the P-Value of occurring.
(c) When rounded and reported with three digits after the decimal point, the P-Value in this hypothesis
test is 0.000. Does this mean that the event you described in part (b) has no chance of occurring?
Why or why not?
(d) If this hypothesis test is performed at the 1% level of significance, do the researchers reject the null
hypothesis or fail to reject* the null hypothesis? Explain.
(e) If this hypothesis test is performed at the 1% level of significance, what do the researchers conclude
about whether-or-not the proportion of American households that have four dogs exceeds 0.13?
(f) If, in reality, the proportion of American households that have four dogs is at least 0.13, then
determine whether the researchers made a Type I or Type II error with their decision in this
hypothesis test (the decision you reported in your answer to part (d)). If either a Type I or a Type II
error is made, state which kind of error (Type I or Type II) is made and explain why; if no error has
been made, explain why.
