Answer:
1) a. Move farther into the tails
2) a. Decreases
Step-by-step explanation:
Hello!
1)
Let's say for example that you are making a confidence interval for the mean, using the Z-distribution:
X[bar] ± 
* 
Leaving all other terms constant, this are the Z-values for three different confidence levels:
90% 
95% 
99% 
Semiamplitude of the interval is
d= *
Then if you increase the confidence level, the value of Z increases and so does the semiamplitude and amplitude of the interval:
↑d= ↑ *
They have a direct relationship.
So if you change α: 0.05 to α: 0.01, then the confidence level 1-α increases from 0.95 to 0.99, and the boundaries move farther into the tails.
2)
The significance level of a hypothesis test is the probability of committing a Type I error.
If you decrease the level from 5% to 1%, then logically, the probability decreases.
I hope this helps!
Answer:
G = 2/3
Step-by-step explanation:
-13G + 10 = 2(-5G + 4) Distribute the 2 to (-5G + 4)
-13G + 10 = -10G + 8
+13G +13G Add 13G to both sides
10 = 3G + 8
-8 -8 Subtract 8 from both sides
2 = 3G Divide both sides by 3
2/3 = G

Answer: =4.4n-13
Step-by-step explanation:
Let's simplify step-by-step.
2n−9−(−2.4n+4)
Distribute the Negative Sign:
=2n−9+−1(−2.4n+4)
=2n+−9+−1(−2.4n)+(−1)(4)
=2n+−9+2.4n+−4
Combine Like Terms:
=2n+−9+2.4n+−4
=(2n+2.4n)+(−9+−4)
=4.4n+−13
Step-by-step explanation/Answer:
<u><em>The value for h(3) is 1.</em></u>
<u><em>Coordinate (3,1)</em></u>
The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.
So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:
<u><em>Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.</em></u>
Answer:
4times1/4(y-(-25/4))=(x-(-3/2)) small 2
4p(y-k)=(x-h)small 2
something like that I belive
or just y>xsmall2+3x-4
