Given that the population proportion is 0.82, the Normal distribution will provide a good approximation to the true sampling dis

Drupady [299]

Answer:

Then solution as long as n ≥ 56

Step-by-step explanation:

The Normal distribution will provide a good approximation to evaluate proportion tests when the following conditions are met:

n*p₀ > 10

n*q₀ > 10

As p₀ = 0,82 q₀ = 0,18 n = 13 30 56 and 100

We test:

A) n = 13 n*q₀ = 13*0,18 = 2,34 2,34 < 10

B) n = 30 n*q₀ = 30*0,18 = 5,4 5,4 < 10

C) n = 56 n*q₀ = 56 * 0,18 = 10,08

n*p₀ = 56 * 0,82 = 45,92

D) n = 100 n*q₀ = 18

n*p₀ = 82

If we test 55 we find that 55*0,18 = 9,9

Then solution as long as n ≥ 56

20 POINTS * A circle has a radius of 6. An arc in this circle has a central angle of 48°

storchak [24]

Answer:

$\frac{8\pi}{5}$

Step-by-step explanation:

Since this is a degree we going to use the arc length formula

$2\pi \times( r)( \frac{x}{360)}$

where x is the central angle measure and r is the radius.

The radius is 6 and the central angle is 48 so let plug that in the formula

$2\pi \times (6)( \frac{48}{360} )$

Multiply 2 pi by 6

$12\pi \times ( \frac{48}{360} )$

$12\pi \times \frac{4}{30}$

$\frac{12\pi}{1} \times \frac{4}{30} = \frac{48\pi}{30}$

$\frac{8\pi}{5}$
