Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed.

a) A 95% confidence interval for a proportion p if the sample has n=100 with p^=0.37, and the standard error is SE=0.05.

b) A 95% confidence interval for a mean μ if the sample has n=60 with x¯=70 and s=12, and the standard error is

c) A 90% confidence interval for a mean μ if the sample has n=20 with x¯=22.5 and s=5.7, and the standard error is SE=1.27.
