The physical plant at the main campus of a large state university recieves daily requests to replace florecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 51 and a standard deviation of 10. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 51 and 61? Do not enter the percent symbol. ans = 95 Incorrect %

The probability that the light bulb replacement requests numbering is between 51 and 61 is 0.34.

Step-by-step explanation:

Let X = number of daily requests to replace florescent light bulbs.

It is provided that

The 68-95-99.7 rule states that:

Compute the probability that the light bulb replacement requests numbering is between 51 and 61 as follows:

**Consider the diagram below.

Thus, the probability that the light bulb replacement requests numbering is between 51 and 61 is 0.34.
