Answer:
b
Step-by-step explanation:
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:

The answer is C, because all those numbers equal 12 :)
Answer: It is
3+3+3+3
Because 3^4 means 3x3x3x3
Answer:
<h2><u>
Graph A</u></h2>
Step-by-step explanation:
We know it must be graph A because when finding the most popularly bought item, the percentages only can go to 100%
So graphs C and D are eliminated.
Also since it never said any flavors were unknown, all the percents have to add up to 100%
So graph B is eliminated.
Only graph A follows the requirements
