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 H ₁: m a = 0.05 is:

A) reject H ₀ if t > 1.6604.
B) reject H ₀ if t - 1.6604.
C) reject H ₀ if t > 1.9842 or Z - 1.9842.
D) reject H ₀ if t - 1.9842.
