A group of adult males has foot lengths with a mean of 29.79 cm and a
standard deviation of 1.76 cm Use the range rule of thumb to identify the
following
Significantly high values are
cm or higher

Answer 1

33.31 cm or higher

Explanation:

Given that:

Mean = 29.79 cm

Standard deviation, s = 1.76 cm

According to the range rule of thumb, values which are greater than or equal to 2 standard deviations from the mean are significantly high values :

Significantly high values are :

Mean + 2(standard deviation)

29.79 cm + 2(1.76)

29.79 + 3.52

= 33.31cm
