We have a null hypothesis that u=3.75, but we are reluctant to accept this as the population value in case the true value is dif

ferent.
An analysis tells us that the probability of rejecting the null hypothesis, if u is really 3.95, is .75.

This probability is:___________?a) The power of the test against the alternative u=3.95b)the probability of a type 1 errorc) beta, which is equal to1 alpha (that is, one minus the significance level)d) the probability of a type 2 errore) equal to the significance level

Answer:

option A

Step-by-step explanation:

To Test

H₀ : μ = 3.75

H₁ : μ ≠ 3.75

now,

If μ = 3.95 then it means H₀ is not true.

then the probability is rejecting the null hypothesis.

Hence, the probability is the power of the test against the alternative μ=3.95

The correct answer is option A

Find the radius of the sphere with a volume of 32/81π cubic yards. Write your answer as a fraction in simplest form. PLEASE HELP

NeTakaya

Area of a sphere = 4(pi)(r)^2
Reverse the equation to find the radius (r)
The answer will be in pi form

32/81(pi)

8/20.25(pi)

Square root of 8/20.25(pi) = radius

r = 2.8(rounded)/4.5(pi)

If 1st and 4tg terms of G.p are 500 and 32 respectively it's second term is ?

bixtya [17]

Answer:

$T_{2} = 200$

Step-by-step explanation:

Given

Geometry Progression

$T_1 = 500$

$T_4 = 32$

Required

Calculate the second term

First, we need to write out the formula to calculate the nth term of a GP

$T_n = ar^{n-1}$

For first term: Tn = 500 and n = 1

$500 = ar^{1-1}$

$500 = ar^{0}$

$500 = a$

$a = 500$

For fought term: Tn = 32 and n = 4

$32 = ar^{4-1}$

$32 = ar^3$

Substitute 500 for a

$32 = 500 * r^3$

Make r^3 the subject

$r^3 = \frac{32}{500}$

$r^3 = 0.064$

Take cube roots

$\sqrt[3]{r^3} = \sqrt[3]{0.064}$

$r = \sqrt[3]{0.064}$

$r = 0.4$

Using: $T_n = ar^{n-1}$

$n = 2$ $r = 0.4$ and $a = 500$

$T_{2} = 500 * 0.4^{2-1}$

$T_{2} = 500 * 0.4^1$

$T_{2} = 500 * 0.4$

$T_{2} = 200$

<em>Hence, the second term is 200</em>
