Question
A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter mile is greater than 14.8 seconds. A random sample of 24 sedans has a mean minimum time to travel a quarter mile of 15.4 seconds and a standard deviation of 2.12 seconds. At α = 0.10, is there enough evidence to support the consumer group's claim? Complete parts (a) through (c) below. Assume the population is normally distributed.

(a) Identify the claim and state H₀ and H₁.

H₀: ____

H₁: ____

(Type integers or decimals. Do not round.)

The claim is the ____ hypothesis.
