Sppose the average annual rainfall for the local area was previously known to be 8 inches. A local meteorologist believes there was above average rainfall from 1997 thru 2001 and argues that the average annual rainfall during this period was significantly different from the overall average annual rainfall of 8 inches. The average annual rainfall recorded from 1997 thru 2001 are given below. S= 1.30, Sample Mean= 6.2, N = 5  What can you conclude?, show step by step procedure

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
