Activity 2: Transportation Cost
A researcher is studying the average cost of traveling for acollege student. As part of their research, they would like tolearn more about the average yearly money spent to travel to andfrom home by air. In a random sample of 130 students, the meantravel cost by air was $1180 with a standard deviation of $535. Usethese sample data to answer the following questions.
A. Use the five-step hypothesis testing procedure outlined belowto determine if there is evidence that the mean travel cost by airfor a college student is different from $1500 yearly. UseMinitab to conduct a single sample mean t-test. Remember to include all relevant Minitab output and identifyyour answers to each step.
Activity 2_A:
Step 1: Check assumptions and writehypotheses.
Activity 2_A:
Step 2: Calculate the test statistic.
Activity 2_A:
Step 3: Determine the p-value.
Activity 2_A:
Step 4: Decide to reject or fail to reject thenull
Activity 2_A:
Step 5: State a “real world”conclusion.
Activity 2_B:
Construct a 95% confidence interval to estimate the mean travelcost by air. Remember to include all relevant Minitab output and toidentify your answer.
Activity 2_C:
What sample size would be needed to construct a 95% confidenceinterval to estimate the average air travel cost for a collegestudent with a margin of error of ±$50? Show all of your workusing the equation editor.
