Let me try . . .

When two lines intersect, they form four (4) angles, all at the same point.
There are two pairs of angles that DON't share a side, and a bunch of other
ones that do share sides. A pair of angles that DON't share a side are called
a pair of "vertical angles".

A pair of vertical angles are equal, but this problem isn't even asking you about
that; it's just asking you to find a pair of vertical angles.

Since you and I are not sitting together at the same table, I can't point to
the drawing and point out different angles to you.  You just have to go
through the choices, and find a choice where both angles are formed from
the same two lines.

The first choice (KRE and ERT) is no good, because KR,  RE,  and  RT
are parts of three different lines.

Check out the other 3 choices, and you're sure to find the only one where
both angles are formed by the same two lines.

Assuming the population of interest is approximately normally​ distributed, construct a 95​% confidence interval estimate for th
nikklg [1K]

Answer: (17.96,20.64)

Step-by-step explanation:

The confidence interval for population mean is given by :-

\overline{x}\ \pm\ t_{n-1,\alpha/2}\dfrac{s}{\sqrt{n}}

Given : \overline{x}=19.3

s= 3.1

n=23, which is a small sample(n<30), so we use t-test.

Significance level: 1-0.95=0.05

Critical value : t_{n-1,\alpha/2}=t_{22,0.025}=2.074

Then , the  confidence interval for population mean will be  :-

19.3\ \pm\ (2.074)\dfrac{3.1}{\sqrt{23}}\\\\\approx19.3\pm1.34\\\\=(19.3-1.34,19.3+1.34)\\\\=(17.96,20.64)

Hence, the 95​% confidence interval for the population mean is (17.96,20.64)
