The quartiles of any distribution are the values with cumulative proportions 0.25 and 0.75. What are the quartiles of the standa

choli [55]

$\mathbb P(X\le Q_1)=F_X(Q_1)=0.25\implies Q_1={F_X}^{-1}(0.25)\approx-0.6745$

where $F_X(x)$ is the CDF for $X\sim\mathcal N(0,1)$ .

By symmetry of the distribution, you then have

$Q_3=-Q_1\approx0.6745$

Hi!

1.)

a:A u B=

$(1.0. - 5. \frac{1}{2} .e)$

(The same elements are written once.)

b:A u C

$(1.0 - 5. \frac{1}{2} .2)$

c:B u C

$( - 5 .1.e.0.2)$

Note:I used dots to mean commas .

Good work!

1. Complete the inequality below to describe the

dezoksy [38]

Domain is the entire span left to right (on the x-axis) that the graph is on. Since the graph goes from x=-4 and ends at x=4, the domain would be from -4 to 4. The circle at -4 is open, so it does not include the point at -4, just everything leading up to it. So, the domain would be

$- 4 < x \leqslant 4$

The range is similar, it is the entire span that the graph goes up and down (on the y-axis). The graph starts at the bottom at y=-2, and ends at y=5. The bottom point (4,-2) is closed, so the graph includes that point, and the top point (-4,5) is open and doesn't include the point. Therefore, the range would be

$- 2 \leqslant x < 5$
