The Sampling Theorem states that when you have a signal x(t) bandlimited to B Hz, then if you sample the signal at frequency f_s higher than or equal to 2B, then you can use the sample to reconstruct the original signal x(t) uniquely.
Yet, if you consider the simple sinusoidal signal...
The marketing manager of humber marketing tests new sales strategy by randomly selecting 250 consumers with a gross income less than $50000, and 250 consumers with a gross income more than 50000. this type of samping is an example of:

You are on the staff at the Post Office. Your job is to find a process to find the average waiting time for service. How do you collect the data, and once it is collected, what do you do next?
Hi All
I am hoping someone can help me out with my problem.
I am sampling data from a flow meter every 10 seconds and storing it into a data historian. The readings are the instantaneous flow rate at the moment the data is sampled.
My problem is that I need to work out (based on the stored...

I assume the "N(12.2, .04)" notation refers to that the distribution of the boxes has mean 12.2 and variance .04. I think 'a' has something to do with the normal distribution, how...
The mean probability of 100 observations is .0422. If you are not given the data for a sample size of 200, how do you find the mean probability of this data using the mean probability you found from .0422?
thanks
