answer question d

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 23 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: 0.01 is there enough evidence to support the consumer group's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. (3) Identify the claim and state H0 and H3. H0: p 514.5 Ha: 1,. > 14.5 (Type integers or decimals. Do not round.) The claim is the alternative hypothesis. (b) Use technology to nd the P-value. Find the standardized test statistic, t. t= 2.07' (Round to two decimal places as needed.) Obtain the P-value. P = 0.025 (c) Decide whether to reject or fail to reject the null hypothesis. Fail to reject Ho because the P-value is greater than a. (d) Interpret the decision in the context of the original claim. There enough evidence at the % level of significance to the claim that the mean minimum time it takes for a sedan to travel a quarter mile is seconds. (Type integers or decimals. Do not round.)
