A sаfety оfficer wаnts tо prоve thаt the average speed of cars driven by a school is less than 25 mph. Suppose that a random sample of 14 cars shows an average speed of 24 mph, with a standard deviation of 2.2 mph. Assume that the speeds of cars are normally distributed. a. What are the appropriate null and alternative hypotheses? Note: Don't worry about inputing symbols if you don't know how. Instead, type the word of the symbol (i.e. x-bar, p-hat, mu, pi) or use proper terminology (i.e. sample mean, population mean, etc.). : [null] : [alth] b. Verify necessary data conditions for using a t statistic. [verify] c. Rounding to 4 decimal places, what is the value of the test statistic? = [TestStatistic] d. Rounding to 4 decimal places, what is the p-value? p-value = [pvalue]
