The three inside angles of a triangle need to equal 180 degrees.

This means X = 180 - 43 - 59 = 78 degrees.

X and Z make a straight line that also needs to equal 180 degrees,

so Z = 180 - 78 = 102 degrees.

Y = 180 - 102 - 13 = 65 degrees.

As the Type II error, β,of a statistical test increases, the power of the test _____________.

shutvik [7]

Answer:

decreases.

Step-by-step explanation:

Type II error is one in which we fail to reject the null hypothesis that is actually false. Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis. The power of Type II error is 1 - $\beta$ . As the power increases the probability of Type II error decreases.

Using the following image, solve the problems below given that U is the midpoint point of TV.

Inessa05 [86]

Answer:

see explanation

Step-by-step explanation:

Given that U is the midpoint of TV, then

TU = UV , substitute values

8x + 11 = 12x - 1 ( subtract 12x from both sides )

- 4x + 11 = - 1 ( subtract 11 from both sides )

- 4x = - 12 ( divide both sides by - 4 )

x = 3

Thus

TU = 8(3) + 11 = 24 + 11 = 35

UV = 12(3) - 1 = 36 - 1 = 35
