Answer:
35
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score = ?
μ is the population mean = 70
σ is the population standard deviation = 14
We were given the z score in the question as: Two and one half standard deviations below the mean
Hence:
= μ - zσ
= 70 - 2.5(14)
= 70 - 35
= 35
The score that is two and one half standard deviations below the mean is 35
