Complete the problem below on engineering paper; do not include the assignment sheet when submitting your homework. Be sure to follow good engineering practice, meaning you must have units attached to all numbers that you write down. Failure to do so will cost you at least $50\%$ of the points available for the problem.

HW #$4$: UNCERTAINTY & STATISTICS

Some chemical reaction is being run inside a sealed gas cylinder. During the reaction, a gaseous product is formed. The pressure $P$ exerted by the gas has been measured five times. A gauge calibrated in units of psig was used. Data from the measurements are provided below:
