Answer:
Improper Fraction :101/2
Mixed Fraction : 50 1/2

Answer:
The hypothesis test is right-tailed.
Step-by-step explanation:
We are given that we want to test the claim that the majority of adults are in favor of raising the voting age to 21.
Let p = <u><em>proportion of adults who are in favor of raising the voting age to 21</em></u>
So, Null Hypothesis, 
: p 
50%
Alternate Hypothesis, 
: p > 50%
As we know that the majority is there when we have more 50% chance of happening of that event.
Here, the null hypothesis states that the proportion of adults who are in favor of raising the voting age to 21 is less or equal to 50%.
On the other hand, the alternate hypothesis states that the proportion of adults who are in favor of raising the voting age to 21 is more than 50%.
This shows that our hypothesis test is right-tailed because in the alternate hypothesis, the greater than sign is included.
Answer:
There are 126 boys on the honor roll and 247 girls on the honor roll.
Step-by-step explanation:
Out of the 1,480 students in Gila Monster High School, a total of 373 of the students made the honor roll.
Let the number of girls that made the honor roll be g.
Let the number of boys that made the honor roll be b.
This means that:
b + g = 373_________________(1)
The number of girls who appeared on the honor roll was 5 less than twice the number of boys.
This means that:
g = 2b - 5___________________(2)
Let us insert (2) in (1):
b + (2b - 5) = 373
=> b + 2b - 5 = 373
3b = 373 + 5
3b = 378
=> b = 378 / 3 = 126
From (1):
b + g = 373
=> 126 + g = 373
g = 373 - 126
g = 247 girls
Therefore, there are 126 boys on the honor roll and 247 girls on the honor roll.
