If the sum is negative or if the signs are different and the negative has a biger absoulute value.
You would get 2 (2x+4). The two factors are the 2, and the (2x+4)
Answer:
<h2>A. 3</h2>
Step-by-step explanation:
Formula for locating the Median of a grouped data = (N+1)/2 th where
N is the total number of defects.
Total defects = 10+18+13+15+9+12
Total defects = 77
Median value = (77+1)/2 th value
Median value = 78/2 = 39th value.
We will cummulate the frequency (number of defects up to the 38th value) and locate the corresponding observation value.
On cummulating:
10+18+13 = 41
<em>We can see that the value of 38 falls on the third column(13), hence the median will be the equivalent number of observations i.e 3.</em>
Therefore the sample median is 3
