Question
A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter mile is greater than
14.6
seconds. A random sample of
24
sedans has a mean minimum time to travel a quarter mile of
15.5
seconds and a standard deviation of
2.09
seconds. At
α=0.10
is there enough evidence to support the consumer group's claim? Complete parts (a) through (d) below. Assume the population is normally distributed.(a) Identify the claim and state
H0
and
Ha.
