A company wants to estimate the fraction theta of defective chips it produces. Say a random sample of 900 chips has 18 defectives. Find a point estimate of theta. Next find a 95% confidence interval for the proportion theta of defective chips and also find a one sided 95% confidence interval for the proportion of defective ones. Refering to this problem, how large a ssample should be taken in order to be confident with probability 95% that the margin of error to estimate the fraction theta of defective chip is 0.025. Refering to this problem, find by how much the sample size increases or decreases if we are willing to increase the margin of error from 0.025 to 0.05 with same 95 probability.
An AB latch operates as follows: If A = 0 and B = 0, the latch state is Q = 0; if either A = 1 or B = 1 (but not both), the latch output does not change; and when both A = 1 and B = 1, the latch state is Q = 1.
An electronic PI temperature controller has an output p of 12 mA when the set point equals the nominal process tmperature. The controller response to step change in the temperature set point of 3 mA
