Test the claim that the proportion of children from the low
income group that drew the nickel too large is greater than the
proportion of the high income group that drew the nickel too large.
Test at the 0.1 significance level.
21 of 40 children in the low income group drew the nickel too
large, and 15 of 35 did in the high income group.

1) You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=20.5σ=20.5. You would like to be 90% confident that your esimate is within 10 of the true population mean. How large of a sample size is required? n = Use a critical value accurate to three decimal places, and do not round mid-calculation — this is important for the system to be able to give hints...
