Answer:
Now we can calculate the p value but first we need to calculate the degrees of freedom for the statistic. For the numerator we have
and for the denominator we have
and the F statistic have 15 degrees of freedom for the numerator and 15 for the denominator. And the P value is given by:
For this case the p value is highert than the significance level so we haev enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviations are not significantly different
Step-by-step explanation:
Information given
represent the sampe size 1
represent the sample 2
represent the sample deviation for 1
represent the sample variance for 2
represent the significance level provided
The statistic is given by:
Hypothesis to test
We want to test if the variations in terms of the variance are equal, so the system of hypothesis are:
H0:
H1:

Your answer would be a=-6.12
Answer:
Solve for X ( The question I did was an example )
Step-by-step explanation:
To solve and equation like 2x+9=30 you will have to isolate the number with a variable. You need to subtract 9 on both sides for that to happen.
2x=21
Now the next step is to divide. You have to divide to get the answer.
x=21/2
x= 10.5
Answer:
28.125 degrees
Step-by-step explanation:
3/8 of 45 is 16.875
45-16.875=28.125
Replace X with 3 and simplify. The answer you would get is 11.
