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): square Next, find the 90% confidence interval for the population proportion of all children from low income families who would draw the nickel too large. b) Margin of error: square c) Confidence interval: square lt plt square d) Does the confidence interval support the claim that more than 40% of children from the low income group draw nickels too large? Confidence interval supports claim Confidence interval does not support claim
