To find the relative frequency of a non-defective unit, we need to calculate the proportion of non-defective units out of the total units checked.
Total units checked = 500
Defective units (non-functioning keys) = 25
Non-defective units = Total units - Defective units
Non-defective units = 500 - 25 = 475
Relative frequency of non-defective units = Non-defective units / Total units
Relative frequency of non-defective units = 475 / 500 = 0.95
In simplest fraction form, the relative frequency of non-defective units is 19/20.
A calculator manufacturing company checks 500 calculator units and 25 of them have non functioning keys. Approximate the relative frequency of a non defective unit from this batch of items. Simplest fraction form
