Think of a project (weather impact last 10 years in Texas) that involves data collection. Collect (weather impact last 10 years in Texas) the needed data, propose several hypotheses and a regression model, and perform the statistical analysis required to calibrate its model or verify/refute its hypothesis.

The long-term average October precipitation in Syracuse is 3.36 inches, with a standard deviation of 1.48 inches. Assuming a normal distribution. What is the probability that less than 1.0 inches of precipitation will occur in any October? Show your work. What is the probability that more than 5.0 inches will occur? Show your work. Draw a labeled sketch to show what area of the normal distribution curve you used to solve the problem.

Children are one of the major concerns of environmental exposure. What is the CDI for a 10 month old child exposed to drinking water contaminated with 10 mg/L nitrate (as N). Assume a 1 year exposure time and a 1 year averaging time. Enter your numerical answer with 2 significant figures in units of mg/kg-d (answers with a different # of significant figures will be marked incorrect).
