WebApr 23, 2024 · 11.7: Steps in Hypothesis Testing. The first step is to specify the null hypothesis. For a two-tailed test, the null hypothesis is typically that a parameter equals zero although there are exceptions. A typical null hypothesis is μ 1 − μ 2 = 0 which is equivalent to μ 1 = μ 2. For a one-tailed test, the null hypothesis is either that a ...

WebAug 16, 2024 · If we assume an exponential distribution, the failure rate can be estimates as λ 1 = f 1 / h 1 failures per hour. Also, the number of failures in an interval t hours is Poisson distributed with rate λ 1 t. Now, there is another collection of machines. These run for h 2 machine hours and fail f 2 times. The failure rate for these is λ 2 = f 2 / h 2
