Extracted text: 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 21 sedans has a mean minimum time to travel a quarter mile of 15.6 seconds and a standard deviation of 2.09 seconds. At a0,10 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 Ho anid H, S 14.5 > 14.5 ror Type integers or decimals. Do not round.) The claim is the altemative hypothesis. Qu (b) Use technology to find the P-value. Find the standardized test statistic, t (Round to two decimal places as needed.) on
