if it's a mix fraction, then you write 22 1/2. if improper fraction, then write 45/2
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 25235
For the alternative hypothesis,
µ > 25235
This is a right tailed test.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 100,
Degrees of freedom, df = n - 1 = 100 - 1 = 99
t = (x - µ)/(s/√n)
Where
x = sample mean = 27524
µ = population mean = 25235
s = samples standard deviation = 6000
t = (27524 - 25235)/(6000/√100) = 3.815
We would determine the p value using the t test calculator. It becomes
p = 0.000119
Since alpha, 0.05 > than the p value, 0.000119, then we would reject the null hypothesis. There is sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area.
The positive trend among the homework scores and the test scores would reveal that if a student does well in homework, he is likely to do well in exams. This can be explained in the sense that the homework will serve as the practice for the student before finally taking the exam.
Hello there!
12/15 and 8/10 don't have the same value.
Reason:
let's simplify both.
12/3 = 4
15/3 = 5
12/15 = 5/4
8/2 = 4
10/2 = 5
8/10 = 4/5
5/4 is greater than 4/5
5/4 > 4/5
Hope i helped!
Let me know if you need anything else!

Hello!
First you had to used apply rule -(-b)=b
Since the denominators are equal to it should be combine by the fractions.
Then add 4+2=6
Finally you had to cancel by the common factor of 3.
Hope this helps! And thank you for posting at here on Brainly. And have a great day! -Charlie :)
