Answer: 34%
Step-by-step explanation:
Given : The distribution of the number of daily requests is bell-shaped and has a [tex]\mu=35[/tex] and [tex]\sigma=6[/tex].
We can see that 41 = 35+6 , it 41 is one standard deviation from mean in the right side . (1)
According to the 68-95-99.7% rule, 68% of the population falls within 1 standard deviation from the mean.
34% (half of 68%) of the population on right side and 34% population on the left side of the density curve. (2)
From (1) and (2), the approximate percentage of light bulb replacement requests numbering between 35 and 41= 34%
