Question: Assuming the distribution being sampled is approximately normally distributed, use the small sample confidence interval for the mean to compute a (a) 90% lower bound

Assuming the distribution being sampled is approximately normally distributed, use the small sample confidence interval for the mean to compute a

(a) 90% lower bound confidence interval for ???? when ???? = 70, ????̄ = 88.6, and ???? =

10.6.

(b) 95% lower bound confidence interval for ???? when ???? = 96, ????̄ = 318.1, and ???? =

43.6.

(c) 99%lower bound confidence interval for ???? when ???? = 55, ????̄ = 13.3, and ???? = 3.4.
