The amount of time, in hours, babies spent sleeping in two different nurseries is shown on the dot plots below.
Nursery 1
A dot plot titled Nursery 1. A number line going from 0.5 to 2.5 in increments of 0.5 is labeled Hours spent napping. There are 0 dots above 0.5, 4 dots above 1, 5 above 1.5, 2 above 2, 1 above 2.5.
Nursery 2
A dot plot titled Nursery 2. A number line going from 0.5 to 2.5 in increments of 0.5 is labeled Hours spent napping. There are 0 dots above 0.5, 3 above 1, 4 above 1.5, 3 above 2, and 2 above 2.5.
Which describes an inference that Mrs. Hardison might make after comparing the means of the two data sets?
The babies in Nursery 1 spent more time napping.
