True or false. Consider a binomial distribution with 16 trials. Look at a table showing binomial probabilities for various values of p, the probability of success on a single trial. For small values of p, the distribution is skewed to the right.

Solutions

Expert Solution

True.

For binomial distribution:-

for small n and small values of p, the distribution is skewed to the right.

for small n and large values of p, the distribution is skewed to the left.

For small p and large n, the binomial distribution approaches symmetry.

For n=16 binomial table

Here up to p = 0.4 the probability decreasing as x increases.

Therefore it is right skewed.
