Answer:
b. His t-score is 40.
Step-by-step explanation:
The middle of the third stanine in a normal distribution means that the standard of nine that is applied has the middle of the third count.
It means that if we divide the normal distribution with the standard of nine we will find the score to be the middle of the third division.
So it will be (1/3*9=3) more than 3.
Which in normal distribution will be more than 30.
The t distribution is approximately normal when the number of degrees of freedom is greater than 30 .
So the best answer is that <u>His t-score is 40 </u> ( choice b).
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:

do what is in the parenthesis first and you multiply first. 3x2 is 6. 6+3 is 9. 9-9 = 0
I think the answer is 0
Area of triangle = 0.5 base height
24 = 0.5 x 6 height
height = 8 inches
