We have
In order to obtain easily the table, we need to clear y
then we evaluate for values of x
if x=0
y=-4(0)+1=1
y=1
if x=1
y=-4(1)+1=-3
y=3
if x=2
y=-4(2)+1=-7
y=-7
if x=3
y=-4(3)+1=-11
y=-11
So the table for the given equation is
x y
0 1
1 -3
2 -7
3 -11
Solution: The formula for mean is:
Where:
is the sum of given observations
is the number of observations
rounded to two decimal places
To find the median, we need to first arrange the data in ascending order but we are already given the data in ascending order.
Therefore, the median is:
Therefore, the median = 1.53
