Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Percentage of students in the class of 2013 has done an internship during their time as an undergraduate student = 38% = p₀
Number of architecture majors = 100
We need to check that whether students at her university had an internship rate that was higher than the national average.
Proportion for her university = 43% = p₁
Here, n = 100
Since n > 30.
so, we can use z-test.
Z-test is generally use to identify whether two means are different when the standard deviation is given.
Hence, it is safe to use the z-test for p.
Therefore, option 'a' is correct.
Answer:
The slope is -4/3.
Step-by-step explanation:
Slope = rise/run. Starting at (3, -1), you go up 4 units and over to the left 3 units to (0,3). Since it's a line of decay, the slope is negative.

Answer:
A. h = 4
B. g = 15
C. b = -6
D. b = 15
Step-by-step explanation:
A. 9h + 8 - 12 = -40
9h - 4 = -40
+ 4 + 4
9h = -36
![\frac{9h}{9} = \frac{-36}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B9h%7D%7B9%7D%20%3D%20%5Cfrac%7B-36%7D%7B9%7D)
h = -4
B. 9 + 6g + 1 = 100
10 + 6g = 100
- 10 - 10
6g = 90
![\frac{6g}{6} = \frac{90}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B6g%7D%7B6%7D%20%3D%20%5Cfrac%7B90%7D%7B6%7D)
g = 15
C. -45 = 28 - 13 + 10b
-45 = 15 + 10b
- 15 - 15
-60 = 10b
![\frac{-60}{10} = \frac{10b}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B-60%7D%7B10%7D%20%3D%20%5Cfrac%7B10b%7D%7B10%7D)
b = -6
D. 37 = 11 +3b - 19
37 = 3b - 8
+ 8 + 8
45 = 3b
![\frac{45}{3} = \frac{3b}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B3%7D%20%3D%20%5Cfrac%7B3b%7D%7B3%7D)
15 = b
