Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.5

Doss [256]

Answer:

Using the Empirical Rule, we find that .997 (99.7%) of students have grade point averages that are between 1.23 and 3.81.

Step-by-step explanation:

Calculate the z-scores corresponding to a GPA of 1.23 and 3.81.

$\displaystyle z=\frac{1.23-2.52}{.43} = \frac{-1.29}{.43}= -3$
$\displaystyle z=\frac{3.81-2.52}{.43}= \frac{1.29}{.43} =3$

We want to find the area between the z-scores of -3 and 3.

The Empirical Rule tells us that 99.7% of the data lies within three standard deviations under the normal curve.

Therefore, the area between -3 < z < 3 is about .997, or around 99.7%.

For a continuous random variable x, the probability density function f(x) represents

jarptica [38.1K]

Answer:

Option d.

Step-by-step explanation:

we know that

The graph of a continuous probability distribution is a curve. Probability is represented by area under the curve.

The curve is called the probability density function (abbreviated as pdf).

We use the symbol f(x) to represent the curve

therefore

The probability density function f(x) represents . the height of the function at x.
