Researchers Determined That 60 Puffs Tissues Is the Average Number $\mu$

question 4

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: $\mu$ < 60.The correct rejection region for $\alpha$ = 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.
