Answer:

the mean of the snowfall amounts? is:

18.8 inches

Step-by-step explanation:

We are given a town's yearly snowfall in inches over a 10-year period as:

2001 14

2002 12

2003 21

2004 26

2005 19

2006 15

2007 22

2008 17

2009 24

2010 18

We have to find the mean

Mean is the ratio of sum of all observations to the total number of observations

Hence, Mean =  (14+12+21+26+19+15+22+17+24+18)/10

                      =18.8
