Select the correct choice below and fill in the answer​ box(es) to complete your choice.
A.
The adult male foot length of 30.4 cm is significantly low because it is less than

enter your response here cm.
​(Type an integer or a decimal. Do not​ round.)
B.
The adult male foot length of 30.4 cm is significantly high because it is greater than

enter your response here cm.
​(Type an integer or a decimal. Do not​ round.)
C.
The adult male foot length of 30.4 cm is not significant because it is between

enter your response here cm and

enter your response here cm.
​(Type integers or decimals. Do not​ round.)

To answer this question, we need additional context about the distribution of adult male foot lengths—specifically the mean and standard deviation—so that we can determine whether a foot length of 30.4 cm is significantly low, significantly high, or within a typical range.

To proceed, I need the following details:

1. **The mean foot length** of adult males.
2. **The standard deviation** of adult male foot lengths.
3. **The definition of "significant"** in this context—whether it's within a certain number of standard deviations from the mean (e.g., typically 2 standard deviations for significance in statistics).

Once I have these values, I can help you fill in the correct choices and thresholds.

Would you like to clarify or provide these details?

Analyze whether a 30.4 cm adult male foot length is statistically significant using the normal distribution and Z-scores. Learn how to determine whether this measurement is significantly low, high, or within a typical range based on standard deviation and the mean. Ideal for high school students studying Grade 10-12 statistics.
