## Step 1<br />The problem is asking us to determine the nature of the data set, specifically the heights of students in 12th grade. The options provided suggest that the data set could be symmetric, skewed right skewed left.<br /><br />## Step 2<br />In a symmetric data set, the mean and median are nearly the same. This is because the data points are evenly distributed on both sides of the mean and median.<br /><br />## Step 3<br />In a skewed right data set, the mean is more than the median. This is because there are a few large measurements that pull the mean away from the median towards the right.<br /><br />## Step 4<br />In a skewed left data set, the mean is less than the median. This is because there are a few small measurements that pull the mean away from the median towards the left.<br /><br />## Step 5<br />The heights of students in 12th grade are generally normally distributed, meaning they are symmetric. This is because the heights of students are not likely to be significantly influenced by a few extremely large or small measurements.
