The frequency distribution of the compressive strength of 20 concrete cube specimen is given in the table.

If μ is the mean strength of the specimens and σ is the standard deviation, the number of specimens (out of 20) with compressive strength less than m μ − 3σ is _________.
    Correct answer is '(0)'. Can you explain this answer?
    Verified Answer
    The frequency distribution of the compressive strength of 20 concrete ...
    Average strength,

    Now,  μ − 3σ = 26.575 - 3 x 3.7 = 15.48
    Thus, no specimen is having compressive strength less than μ − 3σ
