From sixty-five car salespersons, fourteen people answered that they generally sell three cars; nineteen generally sell four cars; twelve generally sell five cars; nine generally sell six cars; eleven generally sell seven cars in one week.

Explanation

According to the given information, the data is

$3 3 3 3 3 3 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 5 5 5 5 5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6 6 7 7 7 7 7 7 7 7 7 7 7$

Hence by plotting the data we have seen that the first quartile of the data is $4$ (that is the starting point of the data) also the median is $4$ (that is marked by the dark line) also the $3^{r d}$ quartile is at $6$ . According to this the data does not has an outlier
