A hardware store sells lightbulbs in the following wattages: 25, 40, 60, 75, 100. At midday, the store sells out of 60-watt bulbs. By how many watts does the median decrease? Answer to the nearest tenth.(1 point)

Answer 1

The median is the middle value when the numbers are listed in numerical order.

Without the 60-watt bulb, the list of wattages would be: 25, 40, 75, 100.

Since there are now an even number of values in the list, the median is calculated by taking the average of the two middle values.

The two middle values are 40 and 75.

(40 + 75) / 2 = 57.5

So, the median decreases by 2.5 watts.
