Question: This question: 1 point(s) possible Subm A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter
This question: 1 point(s) possible Subm 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 21 sedans has a mean minimum time to travel a quarter mile of 15.5 seconds and a standard deviation of 2.12 seconds. At a 0.01 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 H, and H Ho H: (Type integers or decimals. Do not round.) The claim is the null hypothesis (b) Use technology to find the P-value. Find the standardized test statistic, t (Round to two decimal places as needed.) Obtain the P-value. P-O (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. H, because the P-value greater than a (d) Interpret the decision in the context of the original daim There enough evidence at the % level of significance to mean minimum time it takes for a sedan to travel a quarter mile is seconds (Type integers or decimals. Do not round.) the claim that the
