A fireworks show is designed so that the time between fireworks is between one and five seconds, and follows a uniform
distribution.
a. Find the average time between fireworks.
b. Find probability that the time between fireworks is greater than four seconds.
Carbon-14 is a radioactive element with a half-life of about
5,730 years. Carbon-14 is said to decay exponentially. The decay rate is 0.000121. We start with one gram of carbon-14.
We are interested in the time (years) it takes to decay carbon-14. Are the data discrete or continuous?

The data that follow are the square footage (in 1,000 feet squared) of 28 homes.

The sample mean = 2.50 and the sample standard deviation = 0.8302. The distribution can be written as .
What is the percentile of square footage for homes?
