Answer:
The conclusion is that the researcher was correct
Step-by-step explanation:
From the question we are told that
The sample size is 
The sample mean is 
The standard deviation is 
The significance level is 
The Null Hypothesis is 
The Alternative Hypothesis is 
The test statistic is mathematically represented as

Substituting values


Now the critical value for
is

This obtained from the critical value table
So comparing the critical value of alpha and the test value we see that the test value is less than the critical value so the Null Hypothesis is rejected
The conclusion is that the researcher was correct
To get the greatest common factor of a list of numbers, you can use a neat trick.
First, get the greatest common factor of the first two. Then, the greatest common factor of that and the third, and so on.
In this case, we need to get the greatest common factor of 24 and 40.
I'll use Euclid's algorithm (you can look that up in google, it's just a nice way to find the GCF of two numbers)
24, 40
40, 24
24, 16
16, 8
8, 0
So we get 8. Now we need to get the greatest common factor of 8 and 56:
8, 56
56, 8
8, 0
We get 8 again, and that is the greatest common factor of the three numbers.
Hope this helps :)
Answer:
I think u=11
Step-by-step explanation:
A=6a^2
726 divided by 6= 121
square root of 121=11
answer=11
Not quite sure what you are asking...
t stands for time in this formula
if you are trying to solve for t it would be t=d/r or time equals distance divided by rate
hopefully this helps! if not please let me know.
