As the x-values increase, y-values should decrease as the rule for positive correlations is that while one variable increases the other one decreases. In this problem's case, the x values are increasing therefore, the y values must decrease or it would not be a positive correlation.

Answer:

<em>The number of apples in the 12th bag is 9</em>

Step-by-step explanation:

<u>The Mean Value of a Data Set</u>

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

\displaystyle \bar x=\frac{\sum{x_i}}{n}

Where xi is the value of each data and n is the total number of values.

We are given the value of n=12 and the mean number of apples in each bag (8), thus:

\displaystyle 8=\frac{\sum{x_i}}{12}

Multiply by 12

\sum{x_i}=96

This means the sum of all the values is 96. If we add the existing values from the table, considering their frequency, we have:

6*1+7*4+8*2+9*3+10*1=87

Note the sum should be 96, so the 12th bag must have 96-87=9 apples

The number of apples in the 12th bag is 9
