1. For a given binomial distribution with n fixed trials and p, which is the probability of success of each trial, the binomial distribution is skewed left if p=0.50 Select one: True or False 2. Consider a graph of a normal distribution with the mean μμ and standard deviation σσ. The graph will never cross the horizontal axis. This happens because the normal distribution is an exponential function. Select one: True or False 3. Suppose you flip a fair a...
Let X have a binomial distribution with parameters n 25 and p. Calculate each of the following probabilities using the normal approximation (with the continuity correction) for the cases p-0.5, 0.6, and 0.8 and compare to the exact binomial probabilities calculated directly from the formula for b(x;n, P).
