A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter mile is greater than 14,5 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 2.09 seconds. At a=0.05 is there enough evidence to support the consumer group's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. Odve (a) Identify the claim and state Ho and H Ho: H.: (Type integers or decimals. Do not round.) The claim is the hypothesis.
