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

Answer:The girl will get $2,000, the mother $4,000 and the boy $8,000

Step-by-step explanation:

f the amount the girl gets = x

The mother gets twice as much as the girl = 2x

And the boy get twice as much as the mother = 4x


Overall

x + 2x + 4x = $14,000

7x = $14,000

Divide both sides by 7 so

x=$2,000

2x + 3(8 - 3x) = 3
2x + 24 -9x = 3
-7x = -21
x = 3

y = 8 - 3x
y = 8 - 3(3)
y = 8-9
y = -1

Check the math:
2(3) + 3(-1) = 6 - 3 = 3
