Answer:
Total of the frequency = The last values of the cumulative frequency (c.f) = 100
Step-by-step explanation:
From the frequency distribution table given in the question, the cumulative frequency (c.f) can be computed by adding each frequency to the sum or total of the preceding frequencies. This makes the last value of the cumulative frequency (c.f) to be equal to the total of the frequency.
Based on this explanation, we have:
<u>mass </u><em><u>m</u></em><u> (kg) </u> <u> frequency </u> <u> mass </u><em><u>m</u></em><u> (kg) </u> <u> c.f </u>
0 < <em>m</em> ≤ 0.1 2 <em> m</em> ≤ 0.1 2
0.1 <<em> m</em> ≤ 0.2 7 <em>m</em> ≤ 0.2 9
0.2 < <em>m</em> ≤ 0.5 32 <em>m</em> ≤ 0.5 41
0.5 < <em>m</em> ≤ 0.8 46 <em>m</em> ≤ 0.8 87
0.8 <<em> m</em> ≤ 1 13 <em>m</em> ≤ 1 100
From the above, we can observe that:
Total of the frequency = 2 + 7 + 32 + 46 + 13 = 100
The last values of the cumulative frequency (c.f) = 100
Therefore, we have:
Total of the frequency = The last values of the cumulative frequency (c.f) = 100
? + 8 = 11
Subtract 8 from both sides.
? = 3
HG = 8
? + 6 = 9
Subtract 6 from both sides.
? = 3
HI = 3
Answer:
E. None of the above answers is correct
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have groups and on each group from we have individuals on each group we can define the following formulas of variation:
And we have this property
The degrees of freedom for the numerator on this case is given by where k =5 represent the number of groups.
The degrees of freedom for the denominator on this case is given by .
And the total degrees of freedom would be
On this case the correct answer would be 4 for the numerator and 95 for the denominator.
E. None of the above answers is correct
Answer:
Step-by-step explanation:
The radius of a circle is any point from the perimeter to the centre of a circle, it's also half of the diameter. In question 1. the radius is labelled as 35 ft.
