Question

A consumer group claims that the mean acceleration time from 0 to 60 for sedans is 6.3 seconds. A random sample of 33 sedans has a mean acceleration time of 7.2 seconds. Assume the population standard deviation is 2.5 seconds. Let α = 0.05.

Identify the correct hypothesis.

Null: Mean not equal to 6.3

Alternative: Mean equal to 6.3

Null: Mean equal to 6.3

Alternative: Mean less than 6.3

Null: Mean equal to 6.3

Alternative: Mean greater than 6.3

Null: Mean equal to 6.3

Alternative: Mean not equal to 6.3
