Write a script to populate an array, called data_array, with 10 random values. Although you can do this with rand() directly, for this exercise create the array with the zeros() function and then use a loop using for, length(), and rand(), to assign values to the array elements. Compute the sum of the values in data_array, instead of using the sum() function. To do this, you must "accumulate" a result, which means that you first create a variable, called data_array_sum, to hold the accumulating result and initialize it to 0. Then loop through your array, updating the accumulating data_array_sum by adding each data_array value as you go: data_array_sum = data_array_sum + data_array(i); Finally, divide the data_array_sum value by the length of data_array, using the length() function and output the result along with the result of calling mean() on data_array, to show that they are the same.
