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.

A rectangular field is 50 yards wide and 100 yards long. Patrick walks diagonally across the field. How far does he walk

S_A_V [24]

Answer:

Patrick walk approximately 112 yards.

Step-by-step explanation:

Given:

A rectangular field is 50 yards wide and 100 yards long.

Patrick walks diagonally across the field.

Now, to find the distance he walk.

Length of the field = 100 yards.

Width of the field = 50 yards.

Now, to get the diagonal distance we put formula:

$Diagonal = \sqrt{length^2+width^2}$

$Diagonal = \sqrt{100^2+50^2}$

$Diagonal = \sqrt{10000+2500}$

$Diagonal = \sqrt{12500}$

$Diagonal = 111.80$

Therefore, Patrick walk approximately 112 yards.

Multiply her pay per hour times number of hours worked.

For a normal 40 hour week, she is paid 16.34 per hour:

16.34 x 40 = 653.60

Overtime is any hours over 40, so if she works 60 hours, she would have 20 hours of over time.

Multiply 20 hours by her overtime rate:

20 x 24.51 = 490.20

Now add this to her normal 40 hour pay:

490.20 + 653.60 = 1143.80

So her range is from 40 hours: 653.60 to 60 hours: 1143.80

The answer would be A
