7 . For the given of a random variable x and associated probabilities ( given in rows 1 and 2 of the following table ) work out the variance and standard deviation
X 2 3 4 5 6 7 8 9 10 Total
P(x) .05 .10 .30 .20 .05 .10 .05 .10 .05 1.00
8 . Boys of a certain age are known to have a mean weight of μ = 45 Kilograms. A complaint is made that the boys living in a municipal children’s home are underfed. As one bit of evidence, n = 50 boys (of the same age) are weighed and found to have a mean weight of x¯¯ = 41.5 Kilograms. It is known that the population standard deviation σ is 5.6 Kilograms (the unrealistic part of this example!). Based on the available data, what should be concluded concerning the complaint?
