An important measure of the performance of a machine is the mean time between failures (MTBF). A certain printer attached to a word processor was observed for a period of time during which 10 failures were observed. The times between failures averaged 98 working hours, with a standard deviation of 6 hours. A modified version of this printer was observed for eight failures, with the times between failures averaging 94 working hours, with a standard deviation of 8 hours. Can we say, at the 1% significance level, that the modified version of the printer has a smaller MTBF? What assumptions are made in this test? Do you think the assumptions are reasonable for the situation?
Given that the resistors that can be used in the lab have a maxpower rating of 1/8W and the logical voltage values will be 0V or5V at the input, determine an appropriate size for the requiredresistor assuming a .
Consider the interval [0,30]: y[n+2] - 0.6y[n+1] - 0.16y[n] = 5x[n+2]. a.) Find zero-state response if the input is x[n]= 4^(-n)u[n] b.) Find zero-state response if the input is x[n]= cos(2npi/6)u[n]
