Question 18
CENAT1 markNeeds review
The frequency distribution of the compressive strength of 20 concrete cube specimens is given in the table:
f (MPa) | Number of specimens with compressive strength equal to f |
|---|---|
23 | 4 |
28 | 2 |
22.5 | 5 |
31 | 5 |
29 | 4 |
If
is the mean strength of the specimens and
is the standard deviation, the number of specimens (out of 20) with compressive strength less than
is ______Log in to check the answer
