**Assigned: You and some of your friends have decided to determine which ride service arrives faster to pick you up at your residence. Both Uber and Lyft are tested. The variable of interest is arrrival time in minutes from the time you submit your ride request. You collect the data ordering 18 rides from Uber and 18 from Lyft at varying times. The following table is the record of the arrival times:

At the .01 level of significance, is there sufficient evidence that the mean arrival time for Uber differs from the mean arrival time of Lyft?

Complete testing in Minitab and prepare report in Word. Enter the data presented above into a Minitab worksheet. Conduct the test with alpha of .10 and complete the following.

Using the six-step process for each hypothesis test complete the following for the ride arrival time analysis.

F test:

Set up the six-step process and using a folded test.

In your conclusion include only the critical value/critical ratio and p value techniques. Present the Minitab output in your conclusion.

For your interpretation discuss whether the distributions have equal variances. Do not include graphs from the F test. Interpretation: State whether the variances are significantly different and which type of T test you will undertake given the outcome of the f test you just completed.

Determine whether to use Case 2 or Case 3 t- test. Set up the six-step process your selected technique.

In your conclusion present the output from Minitab for:

oCritical value/critical ratio technique

opvalue

oConfidence intervals.
