The given data set is
68, 52, 56, 62, 78, 90, 86, 76, 75, 87
Let us plot the given data in the stem-and-leaf plot, we get

Let us find the mean value of the data.
The mean of the data set is the sum of the data divided by the number of data values
Mean =
sum of all datanumber of data
=
52+56+62+68+75+76+78+86+87+9010
=
73010
= 73
Hence, the mean of the data = 73.
Hence, the option
