Answer:

Mean is 161.55

Step-by-step explanation:

Height (xi)            Frequency(fi)             fixi

160                         4                                 640

161                          6                                 966

162                         5                                  810

163                        5                               815

3231                     20                             3231    

Mean = sigma fixi    =     3231     =    161.55

             sigma fi                 20
