Answer:
81
Step-by-step explanation:
f o g = f(g(x))
Step 1. Solve for g(-3)
-3 - 6 = -9
Step 2. Solve for f(-9)
-9^2 = 81
of 70 inches? Is this usual or unusual?
A. Z-score is 2.56 and is usual. B. Z-score is 2.56 and is unusual
C. Z-score is -2.56 and is usual D. Z-score is -2.56 and is unusual
The corresponding z-score for a height of 70 inches is 2.56, which is considered unusual based on the standard threshold.
Use the concept of statistics defined as:
Statistics is a discipline of mathematics that deals with all aspects of data. Statistical knowledge aids in the selection of the appropriate technique of data collection and the use of those samples in the appropriate analysis process in order to effectively create the results. In short, statistics is an important procedure that assists in making data-driven decisions.
Given that,
The mean height of women: 63.6 inches
The standard deviation of women's heights: 2.5 inches
Height in question: 70 inches
Z-score formula: Z = (X - μ) / σ
The Z-score calculation for a height of 70 inches: Z = 2.56
Z-score interpretation: Unusual (greater than 2)
To find the z-score,
Use the formula:
Z = (X - μ) / σ
Where,
X is the value (in this case, 70 inches),
μ is the mean (63.6 inches),
σ is the standarddeviation (2.5 inches).
Calculating the z-score for a height of 70 inches:
Z = (70 - 63.6) / 2.5
Z = 6.4 / 2.5
Z = 2.56
So, the z-score corresponding to a woman with a height of 70 inches is 2.56.
Now, to determine if this z-score is usual or unusual,
Use the standard z-score table.
Usually, z-scores greater than 2 or less than -2 are considered unusual.
In this case,
The z-score is 2.56, which is greater than 2.
Hence,
The correct answer is B. The z-score is 2.56 which is unusual.
