According to Miller, a 12 oz Miller Lite has 96 calories. Suppose that the actual calorie content varies from bottle to bottle, with a mean of 96 calories and a standard deviation of 5 calories. Suppose also that we will select a random sample of 200 such bottles for analysis.

What is the standard deviation of the distribution of sample means?

Answer #1

Solution :

Given that ,

mean = = 96

standard deviation = = 5

n = 200

sampling distribution of standard deviation

=  / n = 5 / 200=0.3536

= 0.3536

Ok, let’s say there’s about 10 calories per ounce of human blood and let’s assume that vampires have the same daily caloric need as humans: 2,000 calories per day. This would mean that vampires would need about 200 ounces, or 12.50 pints, of human blood per day. This would require the vampire to fully exsanguinate about on 1.5 adult humans per day (night?)! Luckily for us mortals, it turns out that vampires need less than 2,000 calories per day (they...
