Document Summary
Then x is (approximately) normal with mean u=np and standard deviation = npq. For any integer a between 1 and n, S = blood diamond x = number of successes among 700 x is binomial (700, 0. 25: mean = u = np = (700 x 0. 25) = 175. 700 x 0. 25 x 0. 75 = 1: standard deviation of x = = 200 175: z score for the value of 200 = Construct a histogram or stem and leaf display for data. If the data is from a normal population, then the shape would be similar to the curve, that is symmetric and mound shape. Find the iqr and compute the ratio iqr/s. Numerical descriptive measure of the sample value of mean is different. Consider the sample mean and let n be the sample size. Consider a poulation with the distirbution given by the random variable x as follows. Pick a random sample of size n = 2 from this population.
