A). Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed. A 95% confidence interval for a difference in means 12 if the samples have n1=60 with x1 = 252 and s1=51 and n2=140 with x2 = 229 and s2=49, and the standard error is SE=7.78. Round your answers to three decimal places. The 95% confidence interval is Enter your answer; The 95% confidence interval,

value 1 to value 2

B). Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed. A 95% confidence interval for a difference in proportions p1-p2 if the samples have n1=60 with p^1=0.69 and n2=70 with p^2=0.59, and the standard error is SE=0.08. Round your answers to three decimal places. The 95% confidence interval is Enter your answer; The 95% confidence interval, value 1 and value 2
