Answer with Step-by-step explanation:

We are given height of students in inches as:

49,48,41,45 and 47

We have to calculate the mean height.

Mean is calculated by sum of all observations over number of observations.

i.e. Mean=sum of all observations/number of observations

Mean height=(49+48+41+45+47)/5

Mean height=230/5

Mean height=46

Hence, mean height of students is:

46 inches
