Compare Mean and Variance of Two Data Sets
Problem Statement:
The board blocks will generate two data sets, one colored red and the other colored black. When you run the program you will have to compare the means and variances of the two sets of data points.
```/* Code generated by RoboBlockly v2.0 */
double Mean;
double Variance;

printf("Is the mean of the red data higher than the mean of the black data? (Please input yes or no)"+"\n");
scanf("%lf", &Mean);
printf("Is the variance of the red data higher than the variance of the black data? (Please input yes or no)"+"\n");
scanf("%lf", &Variance);
```
