A 99% confidence interval for is given by:
The multiplier is __________ .
A. 2.576
B. 1.96
C. None of the other choices represent a suitable response.
D. 1.282
E. 3
Answer: A. 2.576
Explanation:
We are given
Confidence level = c = 99% = 0.99
α = 1 - 0.99 = 0.01
α/2 = 0.01/2 = 0.005
1 - α/2 = 1 - 0.005 = 0.995
Z(1 - α/2) = Z0.995 = 2.576
(by using z-table)

A. 2.576

A 50% confidence level has a confidence interval of 0.6745. A 90% confidence level has a confidence interval of 1.96. A 99% confidence level has a confidence interval of 2.57. A critical distance is measured 17 times. The mean is 317.6 feet, the sample standard deviation is 0.46 feet. The standard error of the mean value with a confidence level of 90% is (A) (2.57) (0.46) 17 (B) (1.96) (0.46) 17 D. (1.96) (0.46) V17 (D) (0.46) (17) 1.96
