If there is a mistake in the calculations, a row in which it is in include the following: D. 4.
In Mathematics and Statistics, a frequency table can be used for the graphical representation of the frequencies or relative frequencies that are associated with a categorical variable or data set.
Based on the frequency table shown in the image below, the total parts for each row can be calculated as follows;
Total parts = good parts + bad parts
Total parts (row 1) = 43 + 2 = 45 (True)
Total parts (row 2) = 43 + 0 = 43 (True)
Total parts (row 3) = 42 + 3 = 45 (True)
Total parts (row 4) = 39 + 6 = 45 (True), contrary to the total parts of 44.
In conclusion, there is a mistake in row 4 because the total parts should be 45.
