A professor is interested in comparing the characteristics of students who do and do not vote in elections. For a random sample of 114 students who claimed to have voted in the last presidential election, she found a mean CPA of 2.71 and a standard deviation of 0.64. For an independent sample of 123 students who did not vote, the mean CPA was 2.79 and the standard deviation was 0.56. Test at the 5% level of significance if the mean CPA of all students who vote is lower than the CPA of students who do not vote.
Answers
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the mean CPA of all students who vote is lower than the CPA of students who do not vote
Step-by-step explanation:
From the question we are told that
The first sample size is [tex]n_1 = 114[/tex]
The sample mean is [tex]\= x_1 = 2.71[/tex]
The standard deviation is [tex]s_1 = 0.64[/tex]
The second sample size is [tex]n_2 = 123 [/tex]
The sample mean is [tex]\= x_2 = 2.79[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The standard deviation is [tex]s_2 = 0.56 [/tex]
The null hypothesis is [tex]H_o : \mu_1 = \mu _2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 < \mu_2[/tex]
Generally the test hypothesis is mathematically represented as
[tex]t = \frac{\= x_1 - \= x_2}{ \sqrt{ \frac{s_1^2 }{n_1} + \frac{s_2^2}{n_2} } }[/tex]
=> [tex]t = \frac{2.71 - 2.79}{ \sqrt{ \frac{0.64^2 }{ 114} + \frac{0.56^2}{123} } }[/tex]
=> [tex]t = -1.01 [/tex]
Generally given that variance are not equal (the standard deviation squared of both population are not equal ) the degree of freedom is mathematically represented as
[tex]df = \frac{[\frac{s_1^2}{n_1 } + \frac{s_2^2}{n_2} ]}{\frac{[\frac{s_1^2}{n_1}]^2 }{n_1 - 1} + \frac{[\frac{s_2^2}{n_2}]^2 }{n_2 - 1}}[/tex]
=> [tex]df = \frac{[\frac{0.64^2}{114} + \frac{0.56^2}{123} ]}{\frac{[\frac{0.64^2}{114}]^2 }{114 - 1} + \frac{[\frac{0.56^2}{123}]^2 }{123 - 1}}[/tex]
=> [tex]df = 225[/tex]
Generally from the t distribution table the the probability of (t < -1.01) at a degree of freedom of [tex]df = 225[/tex]is
[tex] p-value = P(t < -1.01 ) = 0.15679[/tex]
Generally the value obtained we see that [tex]p-value > \alpha[/tex] so
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the mean CPA of all students who vote is lower than the CPA of students who do not vote

ABX Clothing manufactures expensive jackets for sale to college stores in runs of up to
150. Its cost (in dollars) for a run of jackets is
() = + + .
, ( ≤ ≤ )
(a)ABX Clothing sells the jackets at $90 each. Find the revenue function.
(b) Find the profit function.
(c) How many should ABX Clothing manufacture to make a profit? (Round your answer up to
the nearest whole number.)
Answers
Answer:
a. R(x) = 90x b. -1500 -10x - 0.2x c. 148
Step-by-step explanation:
a. Since we have x jackets produced at a rate of $90 per jacket, the revenue function, R(x) = rate × number of jackets = 90 × x = 90x
R(x) = 90x
b. Since the cost function is C(x) = 1500 + 100x + 0.2x, the profit function P(x) = Revenue function - cost function = R(x) - C(x) = 90x - (1500 + 100x + 0.2x)
P(x) = -1500 + 90x - 100x - 0.2x
P(x) = -1500 - 10x - 0.2x
c. For a profit, P(x) > 0
-1500 - 10x - 0.2x > 0
0.2x + 10x + 1500 < 0
10.2x + 1500 < 0
10.2x < -1500
x < -1500/10.2
x < -147.05
x < -147
So, ABX Clothing needs to produce greater than 147 jackets to make a profit. So, they need to make 148 jackets to make a profit.

The answer is 19.
Step-by-step explanation:
3x+1+12=9x+1
3x+13=9x+1
13=6x+1
12=6x
x=2
3(2)+1+12=19
Answer:
CA = 19
Step-by-step explanation:
3x + 1 + 12 = 9x + 1
combine like terms
3x + 13 = 9x + 1
Subtraction property of equality
3x - 3x + 13 = 9x - 3x + 1
13 = 6x + 1
Subtraction property of equality
13 - 1 = 6x + 1 - 1
12 = 6x
Division property of equality
12/6 = 6x/6
2 = x
Symmetric property of equality
x = 2
Substitute x for 2

The ratio of girls to boys in a primary school is 4:5. If there are 24 girls, how many boys are there? Help!
Answers
Answer:
there are 30 boys
Step-by-step explanation:
If there is 24 girls you divide that by 4 and you get six so that means you multiply with six and you get 30.
A ratio of 4:5 means that for every 4 girls, there are 5 boys.
24 girls / 4 girls = 6
5 * 6 = 30 boys
There are 30 boys if there are 24 girls

Answers
Answer:
The value of the car after one year is $1000
Step-by-step explanation:
$5000 * 0.2 = 1000.
You can say the 20% = 0.2.
So it is depreciated by 0.2.
You multiply the number (5000) by 0.2
5000 * 0.2 = 1000.

Anna found a piece of sediment with a diameter of 0.977 millimeters. Write the size of Anna’s sample in expanded form without exponents
Answers
Answer:
The answer in the expanded form is (0.9 + 0.07 + 0.007) millimeters
Step-by-step explanation:
Here, we want to write the size of the diameter of the sediment in the expanded form without exponents
Thus, we have;
0.977 = 0.9 + 0.07 + 0.007
The size of Anna's sample in expanded form can be written be expanding the decimal places.
The expanded form without exponents is (0.9 + 0.07 + 0.007).
Given:
The given diameter is 0.977 millimeters.
Separate the two decimal place of given number.
[tex]0.977=0.9+0.077[/tex]
Separate the three decimal place of given number.
[tex]0.977=0.9+0.07+0.007[/tex]
The expanded form without exponents is (0.9 + 0.07 + 0.007).
