Write a program that uses the randFloat function to generate two sequences

of $500$ points. Each sequence should have the same variance of $3\mathrm{.}0$ but one sequence

should have a mean of $0\mathrm{.}0$ and the other should have a mean of $-4\mathrm{.}0.$ Compare the

computed and theoretical values of mean and variance.

$($Hint: Use the two given equations to write two equations with two unknowns. Then

solve for the unknowns by hand.$)$

There should be no user input for this section

The output should contain the theoretical and practical values as in part $1$ for both

sequences.
