Advertising regulations require that the potassium content identified on the label of bottled water be within o.01 mg/L of the actual mean concentration. To ensure that the sample mean is within the prescribed bounds with a 99% certainty, calculate the sample size given a standard deviation of 0.04 mg/L 1.
The diameter of steel rods manufactured on two different extrusion machines is being investigated. Two random samples of sizes n1 - 15 and n2 - 17 are selected, and the sample means and sample variances are 8.73 and 0.35 respectively for sample 1 and 8.68 and 0.40 respectively for sample 2. Find a 9096 lower-confidence bound on 01/02

Build a deterministic finite-state machine that accepts all bit strings in which the first and last bits are not the same, and that rejects all other bit strings. This problem requires at least five states. Here are three examples of strings that should be accepted: 01 0010011 11110 Here are three strings that should be rejected: 01010 1 11101
