Let the random variable X have a discrete uniform distribution on the integers 1 ≤ x ≤ 7. Determine the mean, μ, and variance, σ2, of X. Round your answers to two decimal places (e.g. 98.76). μ = σ2 =
This is a uniform distribution with
Since we know that
Probability density function of a uniform distribution is
This implies that
Cummulative density function of a uniform distribution is
a)Since we also know that
Mean of a uniform distribution is the average of its interval
i.e.
b) Also
