Answer True or False for the following questions: 1. The probability density function (pdf) is used to describe probabilities for continuous random variables. 2. The cumulative distribution function (cdf) gives the probability as an area. 3. The amount of time (beginning now) until an earthquake occurs has an uniform distribution 4. Normal distributions are commonly used in calculations of product reliability, or the length of time a product lasts. 6. The exponential distribution has the decay parameter, which says that...
