The relationship between the standard normal random variable z and normal random variable X is that :
alisha [4.7K]

Answer:

(B) The standard normal variable Z counts the number of standard deviations that the value of the normal random variable X is away from its mean

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Positive z-score: Above the mean

Negative z-score: Below the mean

All variables are continuous.

X can be positive or negative, just like Z

So the correct answer is:

(B) The standard normal variable Z counts the number of standard deviations that the value of the normal random variable X is away from its mean

On Sunday they traveled=1/7 of the total distance

Total distance to be traveled=x

On Saturday they covered=(5/7)x

Remaining distance=x-(5/7)x=(2/7)x

Sunday=1/2 of the remaining distance=(1/2)×(2/7)x=(1/7)x

On Sunday they traveled=1/7 of the total distance(x)
