Question 11 the manager of a fleet of automobiles is testing two brands of radial tires and assigns one tire of each brand at random to the two rear wheels of eight cars and runs the cars until the tires wear out. the data (in kilometers) follow. find a 99% confidence interval on the difference in the mean life. car brand 1 brand 2 1 37220 34990 2 43638 41461 3 36240 35500 4 32100 31950 5 37210 38015 6 48360 47800 7 38200 37810 8 33500 33215 round your answers to one decimal place (e. g. 98.7). (a) calculate (b) calculate (c) calculate a 99% two-sided confidence interval on the difference in mean life

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
