To determine the median, we need to set up our numbers from least to greatest, and then place T in later to figure out what T is.
8, 9, 9, 9, 10, 11, 12, 15. Cross out the smallest number with the largest number.
9, 9, 9, 10, 11, 12.
9, 9, 10, 11.
9, 10.
9.5 is our median currently.
Since we need to get a number after 10 to make 10 the median, let's use 12.
8, 9, 9, 9, 10, 11, 12, 12, 15.
9, 9, 9, 10, 11, 12 ,12.
9, 9, 10, 11, 12.
9, 10, 11.
10 is now our median since we inserted 12 into our list.
Your answer is 12.

The number of units produced increases from 2 to 452 as the number of factory workers increases from 0 to 90, which gives;
Part A:
- Yes there is a strong positive correlation
Part B:
- The function is <em>y</em> = 5•x + 2
Part C:
- The slope indicates the number of units produced by each worker daily
- The y-intercept indicates that two units can be produced without workers.
<h3>How can the existence of a correlation and the best fit function for the data be found?</h3>
Part A:
The correlation is the relationship between variables based on statistical data.
From the given table, the difference between consecutive terms of the <em>x </em>and y-values are constant, therefore as the x-values increases, the corresponding y-value increases.
Change in x-values, ∆x = 10 - 0 = 20 - 10 = 30 - 20 = 10
Change in y-values, ∆y = 52 - 2 = 102 - 52 = 152 - 102 = 50
Therefore;
- There is a strong positive correlation between the number of workers, <em>x</em>, and the number of units produced, <em>y</em>.
Part B:
Given that the rate of change of the x-values is constant, and the rate of change of the y-values is a constant, the function relating the <em>x </em>and y-values is a linear function, which can be found as follows;
Slope of the equation, <em>m </em>= ∆y/∆x
Which gives;
m = 50/10 = 5
y - 2 = 5•(x - 0)
The function that best fits the data is therefore;
Part C:
The slope of the function is the coefficient of the variable <em>x </em>in the equation, <em>y </em>= m•x + c
- The slope of the plot, 5, indicates that each worker produces 5 units daily
The y-intercept of the function is the value of the constant term, c, in the equation, y = m•x + c
- The y-intercept of the linear equation, y = 5•x + 2, which is 2, indicates that the initial number of units of products at the factory before workers arrive is 2.
