For the distribution Weibull, what happens as the scale parameter decreases?

OPTIONS

• The location parameter approaches zero.
• The probability density function is compressed to the left.
• The probability density function stretches to the right.
• There is no change.

ANSWER

The probability density function is compressed to the left.

EXPLANATION

The Weibull distribution is the most complex of all the distributions. It is generally used in reliability analysis. It was developed by scientist W. Weibull from Sweden. He developed it for solving problems involving the fatigue levels of materials. As the scale decreases, the probability density function is compressed to the left.
