A population of beetles are growing according to a linear growth model. The initial population (week 0) is Po = 9, and the population after 4 weeks is P4 = 25.
Find an explicit formula for the beetle population after n weeks.
Pn=
After how many weeks will the beetle population reach 113?

Twelve different video games showing substance use were observed and the duration times of game play (in seconds) are listed below. the design of the study justifies the assumption that the sample can be treated as a simple random sample. use the data to construct a 99% confidence interval estimate of μ, the mean duration of game play. 4028 4316 4816 4650 4036 5010 4833 4331 4307
