Question

Researchers looked at the average number of hours of sleep per day in a group of 8 college professors. Calculate the range, standard deviaion, and variance, for the dataset below.

X = {6, 6, 5, 7, 5, 4, 8, 5}

	a.	range = 4 standard deviation (sample) = 1.28 variance (sample) = 1.64
	b.	range = 5 standard deviation (sample) = 5 variance (sample) = 5.5
	c.	range = 4 standard deviation (sample) = 1.28 variance (sample) = 1.28
	d.	range = 4 standard deviation (sample) = 1.64 variance (sample) = 1.28
