Problem # 2 Carbon monoxide (CO) level in the atmpospheric air is critial, and its detection and variability is an important task for keeping the environment clean. A detection device is used to monitor the level of CO in the air. The following data, in ppm, were collected from a location: 7.28 6.98 8.50 6.33 7.34 5.56 3.18 5.56 4.03 4.69 (a) Assess the assumption that the data are normally distributed. (You must usee excel or other statistical softwar to plot the data). Hand-sketched plot will get ZERO (b) There is concern that the device has significant variability in its recording. At a significance level of a = 0.05, test the concern that the standard deviation exceeds 2.0. Show all seven %3D
