#50# (2sf)

Explanation:

When calculating the mean simply add all of the values together then divide by the number of values a general formula could be:

#barx = (sumx)/n#

Where #x# is the values in the list and #n# is the number of values.

#barx = (21 + 23 +76 + 47 +55 +135 + 45+ 30+17)/9#
#barx = 50#(2sf)
