Question

The shape of the binomial distribution is always symmetric. True or False

Answer 1

Answer:

Binomial Distribution. ... The mean of a binomial distribution is p and its standard deviation is sqr(p(1-p)/n). The shape of a binomial distribution is symmetrical when p=0.5 or when n is large.

Step-by-step explanation:

Answer 2

This is about understanding binomial distribution curve.

Statement is false.

• Binomial distribution is said to occur when there are only two possible outcomes that are mutually exclusive.

These 2 outcomes are usually termed success and failure.

For example when a coin is tossed, chance of success of getting a head is p = ½ while failure to get a head is q = 1 - p = ½

• Now, the shape of the binomial distribution is symmetrical when p = 0.5 but skewed when p ≠ 0.5.

• Thus, we can say that the shape of the binomial distribution is not always symmetrical since it can also be skewed at different values.
