he New York Times ran an article about a study in which Johns Hopkins researchers subjected laboratory gloves to stress. Among 240 vinyl gloves, 63% leaked viruses. Among 240 latex gloves, 7% leaked viruses. Using a 0.005 significance level, test the claim that vinyl gloves have a larger virus leak rate than latex gloves.

Question
The New York Times ran an article about a study in which Johns Hopkins researchers subjected
laboratory gloves to stress. Among 240 vinyl gloves, 63% leaked viruses. Among 240 latex gloves, 7%
leaked viruses. Using a 0.005 significance level, test the claim that vinyl gloves have a larger virus leak
rate than latex gloves. Note: a1 = number of successes (leaking) latex gloves a2 = number of successes
(leaking) vinyl gloves, approximately using rounding up or down to next integer.
Answer: Fill in the equality expressions below
H0: Ha: α = a1 = a2 = ?1 = ?2 =
Critical Value = Rejection Region = Test statistic =
Conclusion: Reject H0 Keep H0 P-value = 95% CI =
