Question

A random sample of 1010 adult males had their total cholesterol levels (in mg/dL	ext{mg/dL}) measured:180,190,195,200,205,210,195,200,205,190180,190,195,200,205,210,195,200,205,190Use this sample to construct a 95%95\% confidence interval estimate of the population standard deviation of cholesterol levels.

Accepted Answer

(6.11 mg/dL, 16.22 mg/dL)(6.11\ 	ext{mg/dL},\ 16.22\ 	ext{mg/dL})

Answer

(5.92 mg/dL, 14.09 mg/dL)(5.92\ 	ext{mg/dL},\ 14.09\ 	ext{mg/dL})

Answer

(8.86 mg/dL, 15.14 mg/dL)(8.86\ 	ext{mg/dL},\ 15.14\ 	ext{mg/dL})

Answer

(6.97 mg/dL, 15.48 mg/dL)(6.97\ 	ext{mg/dL},\ 15.48\ 	ext{mg/dL})
