Suppose the time to failure follows an exponential distribution with parameter λ. Based on type II censoring determine the likelihood and the maximum likelihood estimator for λ. Assume that n = 3 and the experiment ends after 2 failures.

Suppose the maximum temperature T on any day in Brisbane in January follows a normal distribution...

Suppose the maximum temperature T on any day in Brisbane in January follows a normal distribution with expectation 31 ◦C (degrees Celsius) and standard deviation 2 ◦C. Any temperature above 35 ◦C is deemed dangerous for older people. Using a ta- ble of the normal distribution or otherwise, find the probability that the temperature in Brisbane reaches a dangerous level on any day in January. Suppose the expected temperature increases by an amount δ due to global warming, while the...

Suppose the amount of protein in a serving of 2 eggs follows a normal distribution with mean 12 grams and standard deviation 1 gram. Let Y denote the amount of protein in a randomly selected serving of 2 eggs. Determine the following probabilities (enter each as a decimal, and round to 4 decimal places): P(Y>10) P(Y≥10) P(Y<12) P(Y=12)

The failure time T (in hours of use) for a particular electronics component follows an exponential distribution with parameter λ. Find the probability that a failure time is somewhere within 1 standard deviation of the mean failure time. Explain in words what you did to solve this, and then tell me your final answer.
