Noise Signals. In engineering simulations, we often want to generate a floating-point sequence of values with a specified mean and variance. The function developed in this chapter allows us to generate numbers between limits a and b, but it does not allow us to specify the mean and variance. By using results from probability, the following relationships can be derived between the limits of a uniform random sequence and its theoretical mean μ and variance σ2:

Write a program that uses the rand_float function developed in Chapter to generate sequences of random floating-point values between 4 and 10. Then compare the computed mean and variance to the theoretical values computed. As you use more and more random numbers, the computed values and the theoretical values should become closer.
