Question

Excercise 98) This table shows the time in seconds it takes to go from 0 to 60 miles per hour for a sample of 10 Tesla S cars and 15 Tesla Standard cars.

Tesla S		Porche Panamera
2.41	2.45	3.16	2.84	2.82
2.03	2.85	3.03	2.97	3.01
2.54	1.72	2.55	3.11	2.76
2.09	2.45	2.94	2.73	3.08
2.53	2.60	2.83	2.74	2.84

1. For each sample, determine median, standard deviation and mean
2. Using “boxplots” compare the graphs

Answer 1

		Porche Panamera
		3.16
		3.03
		2.55
		2.94
	Tesla S	2.83
	2.41	2.84
	2.03	2.97
	2.54	3.11
	2.09	2.73
	2.53	2.74
	2.45	2.82
	2.85	3.01
	1.72	2.76
	2.45	3.08
	2.60	2.84
Mean	2.367	2.894
Median	2.45	2.84
Sd	0.328059954	0.167792389

(b)

From the two boxplots, it is seen that the first sample(Tesla S) is negatively skewed while the second sample(Porche Panamera) is positively skewed.
