3. A consumer group claims that the mean acceleration time from 0 to 60 miles per hour for all 3- cylinder vehicles is 9.4 seconds. A random sample of 33 3-cylinder vehicles has a mean acceleration time from 0 to 60 miles per hour of 10.2 seconds. Assume the population standard deviation is 2.3 seconds. At a = 0.05, can you reject the claim? (a) State the null and alternative hypothesis. Identify which of the two is the claim. Also state the level of significance. ⚫ Ho: H₁: (b) Identify if you are working with a right-tailed, left-tailed, or two-tailed test. (c) Test Statistic: What is the test statistic? What is the standardized test statistic? Show work leading to your final answer. (d) Find the P-value for the standardized test statistic. Show your work using Staterunch. (e) Do you reject or fail to reject Ho? Explain why.
