Answer:

17.28÷(1.32-0.24)x0.6 = 9.6

Step-by-step explanation:

The order of operations are the rules that are used to solve to mathematical expressions. The given order is-

1. Parentheses

2. Exponentiation

2. Division

and Multiplication

3. Addition and Subtraction

Now, solving

17.28 ÷ (1.32-0.24) x 0.6

⇒ (17.28 ÷ 1.08) x 0.6

⇒ 10.368 ÷ 1.08

⇒ 9.6

At a Psychology final exam, the scores are normally distributed with a mean 73 points and a standard deviation of 10.6 points. T

Answer:

The score that separates the lower 5% of the class from the rest of the class is 55.6.

Step-by-step explanation:

Problems of normally distributed samples can be 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 question:

$\mu = 73, \sigma = 10.6$
