The spreadsheet below contains the data about daily revenue, the number of male visitors, the number of female visitors, the number of retail stands, the number of food stands, and the number of performances that the organizer used to create the regression model. The organizer now wants to try excluding the number of male visitors and the number of performances from the model because those variables were not significant. Create a regression model to analyze the relationship between daily revenue and the remaining independent variables. Be sure to include the residuals and residual plots in your analysis.

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
