Answer:
See below
Step-by-step explanation:
The formula for a z-score is
z = (x - µ)/σ where µ is the mean, and σ is the standard deviation.
We are given z = 2.8, µ = 17, and σ = 4. Plug them and and solve for x, which will be her point total..
2.8 = (x - 17)/4
11.2 = x - 17 (multiply both sides by 4 to get rid of the fraction)
28.2 = x (add 17 to both sides)
Yes, this score seems unusual. A z-score of 2.8 puts her in the higher tier of point scorers for the season. She scored 28.2 points in an entire season and was one of the highest scorers, so not many people are scoring points.
*Statistically, an unusual number is a number that is between 2 and 3 standard deviations above the mean. Sarah's score is
2.8 standard deviations above the mean, so by statistical definition, her score is unusual.
The Geometric Mean<span> is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. Below is the solution for the above problem:
</span>First we multiply them: 10 × 1250 = 12,500
Then (as there are two numbers) take the square root: √12,500<span> = </span>111.8034
Answer:
Assume the number is X. What is given can be written as the following:
X < (1/4)*(8X+4)
Multiply 4 on both sides
4X< 8X+4
Subtract 4X+4 from both sides
-4 < 4X
-1<X i.e., X>-1 the number is greater than -1.
