Write your answers for this question on paper and then upload: From sampling 40 taxicab rides in New York City, a survey found that the mean cost of the taxi fare from the sample was $12.04. If the population standard deviation is $8.36, test the claim that the mean cost of a taxicab ride in New York City is less than $15.00. (a) State the null and alternative hypothesis. (b) By hand, find the test statistic z-score. Round to two decimal places. (c) Sketch the sampling distribution labeling the test statistic found in part (b) and compare it to the critical value z-score found in the previous question to make a decision to either reject or fail to reject the null hypothesis.
