Using SPSS!!! ONY SPSS

13. The table shows the costs per mile (in cents) for a sample of automobiles. At α = 0.01, can you conclude that at least one mean cost per mile is different from the others?

Small Sedan	Medium Sedan	Large Sedan	SUV 4WD	Minivan
41	65	60	79	64
39	47	69	58	74
47	61	79	67	57
52	57	71	70	49
44	62	76		68
	50	68

Expert Solution

The hypothesis being tested is:

H0: µ1 = µ2 = µ3 = µ4 = µ5

Ha: At least one means is not equal

The SPSS output is:

The p-value is 0.000.

Since the p-value (0.000) is less than the significance level (0.01), we can reject the null hypothesis.

Therefore, we can conclude that at least one mean cost per mile is different from the others.

Please give me a thumbs-up if this helps you out. Thank you!

The cost per seat-mile on a major U.S. airline is 24.1 cents. In order to estimate the cost of flying a passenger from Pensacola, FL, to Denver, CO, we should multiply 1,184 miles by 24.1 cents.

A pig weighing 200 pounds gains 5 pounds per day and costs 45 cents a day to keep. The market price for pigs is 65 cents per pound, but is falling 1 cent per day. Do a sensitivity analysis of the time to wait to sell (denoted by t) to the keeping cost k. Derive a general expression of S ( t , k ) and evaluate it at k = 0.45 keeping all other constants the same, g =...
