Answer:
There is enough evidence to support the claim that the percentage of residents attending college in that age-group is greater than 23.8%
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 610
p = 23.8% = 0.238
Alpha, α = 0.01
Number of 18-24 year-old attending college , x = 178
First, we design the null and the alternate hypothesis
This is a one-tailed(right) test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.0009
Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject the null hypothesis.
Conclusion:
Thus there is enough evidence to support the claim that the percentage of residents attending college in that age-group is greater than 23.8%
Answer:
a) 64
b) 9
c) 1
d) 49
Step-by-step explanation:
8^2 = 64
same as 8*8
1^2 = 1
same as 1*1
3^2 = 9
same as 3*3
7^2 = 49
same as 7*7
Answer:
$189
Step-by-step explanation:
Let their total amount of spending money be x
given that $135 they spent is 5/7 of their total spending money,
mathematically:
135 = (5/7) x (multiply both sides by 7)
135 (7) = 5x
945 = 5x
5x = 945 (divide both sides by 5)
x = 945 / 5
x = 189
For every +1 input, the output is -125
38/1000
This is because the 0.0 is in the tenths place, 0.03 is in the hundredths place, and 0.038 is in the thousandths place.
