question 55

Multiple Choice

Researchers determined that 60 Puffs tissues is the average number of tissues used during a cold.Suppose a random sample of 100 Puffs users yielded the following data on the number of tissues used during a cold: = 52 and s = 22.Suppose the alternative we wanted to test was H₁: μ < 60.The correct rejection region for α = 0.05 is:

• A)reject H₀ if t > 1.6604.
• B)reject H₀ if t < −1.6604.
• C)reject H₀ if t > 1.9842 or Z < −1.9842.
• D)reject H₀ if t < −1.9842.
