a group of adult males has foot lengths with a mean of 31.99 cm and a...
Homework Answers
Let μ = 31.99 and σ = 2.39
By range rule of thumb;
Maximum value = μ + 2σ = 31.99 + 2*2.39 = 31.99 + 4.78 = 36.77
Minimum value = μ - 2σ = 31.99 - 2*2.39 = 31.99 - 4.78 = 27.21
Significantly low values are 27.21 or lower
Significantly high values are 36.77 or higher
So, an adult male foot length of 27.21 or lower would be significantly low.
***please ask if you have any doubts.Happy to help you.Thank you.
