The only instruction I got is failure rate for exponential distribution as image attached

Hi, I have this question: If random variable T is uniformly distributed over [a, b] , what is its failure rate? Please help

So how to determine when problem has optimal solution. infinite or no solution depending on lambda??

Hi All, I am struggling with minimization(maximization) problems which needs to be solved graphically but they have unknown parameter in objective function: For example: f = 2x_1 + \lambda x_2(min) for conditions: -x_1 + x_2 \leq 3 x_1 + 2x_2 \leq 12 3x_1 -x_2 \leq 15 x_i \geq 0 More than...

Hi, If I have a sample of 150 data how to chose between tests of exponentiality? I mean is there any way to find the most appropriate test for my case judging on my data number,or maybe skewness, kurtosis, etc? Or there are 2 or 3 frequently used tests (Pearson maybe) which are most used...

Any way to solve the following limit without using series: lim (3^x (3*(x^2)+2) / (7+x)! when x->infinity Regards

No I cannot think anything of these for passenger arrivals. They are completely random in my case. Only time of observation is peak hour in the morning.

Sorry I missed you here. Maybe you mention an example?

No I cannot think of one process that connects passenger arrivals at the bus stop because schedule of bus is not fixed.Anyway its kind of strange just to say not correlated.Thought maybe can be a more specific math speech style :))

Yes thank you please continue

Of course not but there is need for further words on this I think.

It does but for the adviser is not acceptable just to write they do not have a causal correlation because there is a "why" after that

arrival of one client:)

Independence, memory less etc. I am trying to do the translation bu always failing on it :)

Actually describing the process of arrivals for clients in a shop: Getting difficulties with math describing of the process: I wrote down three properties of Poisson but adviser is asking to describe very carefully how we understand these properties to reason that process is Poisson without...
