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 ...

Note that this is a two-sided test, and we would reject the null hyposthesis if the \(p\)-value is either too small (i.e., less or equal to 0.025) or too large (i.e., greater than or equal to 0.975) for a 95 % significance level test. oundle triathlon 2023WebAug 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 oundle vw
