Consider a normal distribution with a mean of 14 and variance of 26. What is the Z score for the value of 16?
Solution :
Given that ,
mean =
= 14
variance =
2 = 26
standard deviation = =
2
=
26 = 5.10
x = 16
Using z-score formula,
z = x -
/
z = 16 - 14 / 5.10
z = 0.39

QUESTION 5 Consider a sample of size 26 from a normal distribution with mean 17.4 and s 2.69. What is the value of a two-sided 98.O % confidence interval for the mean? O (16.089,18.711) (16.797,18.003) (16.257,18.543) (13.873,20.927) (17.143,17.657) (16.708,18.092) QUESTION 6 Consider a sample of size 12 from a normal distribution with mean 0.5 and s 0.05. What is the value of a two-sided 99.0 % confidence interval for the mean? (0.499,0.501) (0.455,0.545) (0.461,0.539) O (0.498,0.502) (0.487,0.513) (0.499,0.501)
In a normal distribution, the mean corresponds to: Standard Score: z = Percentile: Which of the following statements are TRUE about the normal distribution? Check all that apply. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean. The mean corresponds to the z-score of 1. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean. A z-score is the number of standard deviations a...

(5) If F(x) is the CDF of a Normal distribution with mean 50 and variance 16, and G(x) is the CDF of a Normal distribution with mean 25 and variance 9, is the function H(x) = (1- c)F(x) + cG(x) also a legitimate CDF (for any positive fraction c)? What’s the pdf for H(x)? Can you find the mean and the variance for H(x) in terms of those parameters for F(x) and G(x)?
