FORMULA:

Lower Quartile (Q1) = (N + 1) × 1 / 4.
Middle Quartile (Q2) = (N + 1) × 2 / 4.
Upper Quartile (Q3 )= (N + 1) × 3 / 4.

GIVEN:

N(numbers) = 8

Now, (Q1) = (8 + 1) × 1/4

9/4
2.25

(Q2) = (8 + 1) × 2/4

9 × 2/4
9 × 1/2
9/2
4.5

(Q3) = (8 + 1) × 3/4

9 × 3/4
27/4

Find the height of a trapezoid if the bases have lengths of 6 and 17 and the area of the trapezoid is 46 square units.

Aleksandr [31]

Answer:

4 units

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the bases

here A = 46, a = 6 and b = 17, hence

46 = $\frac{1}{2}$ h(6 + 17) ( multiply both sides by 2 )

92 = h(23) ← divide both sides by 23 )

h = $\frac{92}{23}$ = 4 units

Student Debt – Vermont: The average student loan debt of a U.S. college student at the end of 4 years of college is estimated to

mezya [45]

Answer:

The confidence interval is (24116.3878,24883.6122).

Step-by-step explanation:

We are given the following information in the question:

Population mean, $\mu$ = $23,500

Sample mean, $\bar{x}$ = $24,500

Sample standard deviation,s = $2,800

Sample size, n = 146

Confidence interval:

$\bar{x} \pm t_{critical}\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at}~\alpha_{0.05} = \pm 1.655436$

$24500 \pm 1.65543(\frac{2800}{\sqrt{146}} ) = 24500 \pm 383.6122 = (24116.3878,24883.6122)$

The confidence interval is (24116.3878,24883.6122).
