Question: Determine the sample size required for a large sample (a) 90% upper bound confidence interval for ???? when ???? = 0.25 and the desired margin

Determine the sample size required for a large sample

(a) 90% upper bound confidence interval for ???? when ????̇ = 0.25 and the desired margin of error is ???????? = 0.04.

(b) 95% upper bound confidence interval for ???? when ????̇ = 0.65 and the desired margin of error is ???????? = 0.03.

(c) 99% lower bound confidence interval for ???? when ????̇ = 0.50 and the desired margin of error is ???????? = 0.02.

(d) 95% lower bound confidence interval for ???? when ????̇ = 0.90 and the desired margin of error is ???????? = 0.035.
