1. Write a program to calculate simple statistics (use the program developed below as a guide). Use an array to hold the data set input by the user and use loops to calculate the mean and variance of the data. Also compute the standard deviation. /* Compute the mean, standard deviation, and variance for a set of sample data * / #include main () { int count, i; float mean, var, dp, stddev; mean = 0.0; var = 0.0; count = 10; for (i=1;i Please, modify the program to accept data from a file. The file can be a simple column of numbers that you can generate using a text editor. Use fscanf to determine when the values read from the file are exhausted.
