Answer:
C. 4.88
Step-by-step explanation:
The computation of the Value of F is shown in the attachment below.
Data provided in the question is as follows
Number of treatments = 4
Total number of observations = 12 × 4 = 48
SST = 210
SS = 840
So, SSW is
= SS - SST
= 840 - 210
= 630
Based on the above information, the value of F is 4.88
Hence, the correct option is C. 4.88
Answer:
68 %
Step-by-step explanation:
The Empirical rule formula states that:
• 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
• 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
• 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
Mean of 96 and a Standard deviation of 17
Applying , the first empirical rule for 1 standard deviation from the mean, we have:
μ - σ
96 - 17
= 79
μ + σ
96 + 17
= 113
Therefore, the percentage of IQ scores that are between 79 and 113 is 68%
Answer:
Area of uncut triangle=1/2×9×7
=31.5in^2
Area of cut part=4×2=8in^2
Therefore,
<em><u>Area </u></em><em><u>of </u></em><em><u>figure=</u></em><em><u>3</u></em><em><u>1</u></em><em><u>.</u></em><em><u>5</u></em><em><u>-</u></em><em><u>8</u></em>
<em><u>=</u></em><em><u>2</u></em><em><u>3</u></em><em><u>.</u></em><em><u>5</u></em><em><u>i</u></em><em><u>n</u></em><em><u>^</u></em><em><u>2</u></em>
16 × 6.7 = 107.2
your answer is 107.2
