4. Estimating the population proportion, p, of all children from low income families who would draw the nickel too large.
Give all answers correct to 3 decimal places.
a) The best point estimate for the value of the population proportion p of all children from low income families who would draw the nickel too large is (hint: this number was an answer in an earlier question in this exam):
Next, find the 99% confidence interval for the population proportion of all children from low income families who would draw the nickel too large.
b) Margin of error:
c) Confidence interval: < <
d) Does the confidence interval support the claim that more than 40% of children from the low income group draw nickels too large?
