Answer with explanation:
The data points in the question are given by:
35, 48, 36, 48, 43, 37, 43, 39, 45, 46, 40, 35, 50, 38, 48
On making a table of these data values based on the frequency of these points i.e. the number of times they appear in the data.
 Points Frequency
 35 2
 36 1 
 37 1
 38 1
 39 1
 40 1
 43 2 
 45 1
 46 1 
 48 3
 50 1
Hence, the dot plot will be a horizontal line such that the number are at a increment of 1 starting from 35 and shows up to 50.
This means that there are 1 dots over: 36,37,38,39,40,45,46 and 50.
2 dots over 35 and 43.
and 3 dots over 48.
The correct dot plot is attached to the answer.
