Consider an experiment in which a fair coin is tossed 10 times.
Let the random variable X represent the number of heads in the 10
trials. Compute P(X = 4) using: (a) the binomial PMF, which
provides the exact solution, and (b) the central limit
approximation (i.e., Gaussian approximation) to the binomial using
the inclusion of the ±0.5 terms from the De Moivre-Laplace
formula
the result: P[-0.9486 <= Z <= -0.3162]
-0.3754 - 0.1711 = 0.2034
show the process and how that result is obtained. show the table
and how from P[-0.9486 <= Z <= -0.3162] you
obtain -0.3754 - 0.1711. Explain
