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
You solve for y and get
y=3/4x-5
Slope is 3/4
Y intercept is -5
It will take him 182 because when you divide 2175 by12 u get 181.25 and you have to add a day for the point .25
