Harry measured the temperature at 2 p.m. at the same spot in his garden and recorded his results to the nearest degree $(^{o} F)$ for each day of the year (365 days). On approximately what percent of the days was the temperature above $40^{o} F$ but less than $70^{o} F$

Solution

The correct option is B 70%
Number of days for which the temperature was above $40^{o} F$ but less than $70^{o} F$ is found by adding the frequencies for the groups 40 to 50, 50 to 60, and 60 to 70.

Which is (approximately) 130 + 70 + 50 = 250

As a percentage of the year, this is: $\frac{250}{365} \times 100 = 68.5 %$
or approximately 70%
