This week’s and last week’s readings have included the binomial, poisson and normal distributions. each provides very accurate results when used in the circumstances for which they are intended in quality engineering. however, the binomial and poisson distributions can get very cumbersome to calculate as the scale of the sample size grows. the tables of values provided in most text books typically don’t provide values for very large sample sizes. (the largest sample size supported in our text appendices is 36.) as a result, it is conventional to use the normal distribution as an approximation of either the binomial or poisson distribution as sample sizes grow. discuss what it means to use the normal distribution as an approximation for the binomial or poisson distribution. why does it work? what are the strengths or weaknesses of doing so? (hint: think about the center versus the tails.)

The clayton family’s pool has vertices at the coordinates (0, 2), (0, 5), (2, 5), (2, 6), (5, 6), (5, 1), (2, 1), and (2, 2). if each grid square has an area of 9 square feet, what is the area of the pool?

The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a mean of $235 and a standard deviation of $20. according to the standard deviation rule, how much did almost all (99.7%) of the students spend on textbooks in a semester?
