Question

A group of adult males has foot lengths with a mean of 26.82 cm and a standard deviation of 1.14 cm. Use the range rule of thumb for identifying significant values to identify the limits separating values that are significantly low or significantly high. Is the adult male foot length of 24.1 cm significantly low or significantly​ high? Explain.

Answer 1

Answer:

The adult male foot length of 24.1 cm is significantly low because it falls outside the range of significant values.

Step-by-step explanation:

For the given foot length data:

Mean = 26.82 cm

Standard Deviation = 1.14 cm

Two standard deviations below the mean:

26.82 - (2 * 1.14) = 24.54 cm

Two standard deviations above the mean:

26.82 + (2 * 1.14) = 29.1 cm

The range for significant values is between 24.54 cm and 29.1 cm.

Therefore, an adult male foot length of 24.1 cm is significantly low because it falls outside the range of significant values.
