The problem statement for 1(a) contains contradictory information. Specifically, using the given values for "only Algebra" and "Algebra" leads to $x=6$. However, when $x=6$ is used to calculate the number of students studying Statistics, it results in a number greater than the total class size, or it contradicts other given information.

To proceed, I will make the following assumption: The values for "only Algebra", "Algebra", "both Algebra and Statistics", and "neither" are consistent, and we will derive $x$ from these. The stated number of students for "Statistics" ($10x+13$) will be considered inconsistent and will be recalculated based on the derived $x$ and other consistent information
