Find the mean and median.

please mark brainiliest pleas

Step-by-step explanation:

when finding the mean...we first arrange the given data in ascending or descending order

but here the data given is already arranged

mean = sum of data/ number of data

mean = 28+57+58+64+69+74+79+80+83+85/10

mean = 677/10

mean = 67.7

when finding the median

we arrange the given data in ascending or descending order

median = we are going to get the two middle numbers and we add them and we divide them by 2

median = 69+74/2

median = 143/2

median = 71.5

hope that will help
