Question

3. A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter mile is greater than 146 seconds. A random sample of 24 sedans has a mean minimum time to travel a quarter mile of 15.2 seconds and a standa deviation of 2.11 seconds. At = 0.10 is there enough evidence to support the consumer group's claim? Complete parte da through (d) below. Assume the population is normally distributed. (a) Identify the claim and state Ho and Ha. Ho: (1) __ - (2) Hai (3) - (Type integers or decimals. Do not round.) The claim is the (5) - - 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. PE (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. (6) - - Ho because the P-value (7) - - greater than a (d) Interpret the decision in the context of the original claim. There (8) enough evidence at the % level of significance to (9) - the claim Seconds that the mean minimum time it takes for a sedan to travel a quarter mile is (10) - (Type integers or decimals. Do not round.) (1) OO (2) O SO2 (3) OP (4) Os Oz (5) O null O o? O O O O O O O alternative OH O Op tvu Oo (6) (9) O Reject Fail to reject (7) O O (8) O is not is is not is support reject O O less than or equal to greater than or equal to (10) O greater than O equal to o less than O not equal to

could you please show your work on how you get the value of (P) please? thats where im having a lot of trouble
