A random sample of size nequals250 yielded ModifyingAbove p with caretequals0.48. a. Is the sample size large enough to use the
large sample approximation to construct a confidence interval for p? Explain. b. Construct a 90% confidence interval for p. c. Interpret the 90% confidence interval. d. Explain what is meant by the phrase "90% confidence interval."
First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.
