Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "x3" was replaced by "x^3". 2 more similar replacement(s).

((3•(x2))+(9•(x2)))-3x3

((3 • (x2)) + 32x2) - 3x3

(3x2 + 32x2) - 3x3

Pull out like factors :

12x2 - 3x3 = -3x2 • (x - 4)

-3x^2 • (x - 4)

Assume that women have heights that are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches.

Maurinko [17]

Answer:

Q3 = 65.7825.

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.

In this problem, we have that:

$\mu = 63.6, \sigma = 2.5$
