The carbon monoxide (CO) level in a manufacturing plant is supposed to be about 50 parts per million (ppm). However there is concern that actual CO levels are higher than the acceptable level.Five CO measurements are taken at various times during the day and reading are given below. 58 63 48 52 68

(a)At 5% level of significance test whether the mean CO level is higher that 60 ppm.

(b)Find a 95% confidence interval for the mean CO level.

A 0.020 mol sample of carbon monoxide (CO) is placed in a cylinder fitted with a movable frictionless piston. This gaseous sample - initially at volume Vi = 4.00 L - has a pressure of 0.400 atm - identical to the external pressure. This gaseous sample then undergoes a cyclic process. Throughout the cyclic process, the sample is thermostatted at a Kelvin temperature T. The details of this cyclic process: First, a two-step expansion carried out as follows:    The...
