Need help with part C I am stuck trying to find the p value.

A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter mile is greater than 14.7 seconds. A random sample of 20 sedans has a mean minimum time to travel a quarter mile of 15.3 seconds and a standard deviation of 2.11 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 Ho and Ha. S 14.7 Hai 14.7 (Type integers or decimals. Do not round.) The claim is the alternative hypothesis. (b) Use technology to find the P-value. Find the standardized test statistic, t. 1= 1.27 (Round to two decimal places as needed.) Obtain the P-value. P = 0.219 (Round to three decimal places as needed.)
