To get this answer, you need to divide 6.5 by 5. 6.5/5=1.3 since the measure is in feet, each section is 1.3 feet long.

You have to use division in this case. 6.5 / 5 = 1.2. Each piece of wood is 1.2 feet long. Drawing a graph is also a helpful way to solve this kind of problem too... but I recommend division since it is faster and quicker.

Compute z-score. Given ~ n(12,2.5),find z score when x =17
Anestetic [448]

Answer:

The desired z-score is 2.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

n(12,2.5)

This means that \mu = 12, \sigma = 2.5

z score when x =17

This is Z when X = 17. So

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

Z = \frac{17 - 12}{2.5}

Z = 2

The desired z-score is 2.
