according to W.A. Wallis and H.V. Roberts statistics is a body of methods for making wise decisions in the face of uncertainty

we know that in statistics we make inference and estimate value of parameters or in other words we think about a possible outcome with some uncertainty . results by any method of statistics are not perfect.i.e. results obtained with the help of any method of statistics can not exactly equal to true results .estimated results are always different from exact result . i.e. result drawn from inference always contain some uncertainty in it .

due to this uncertainty in results drawn , we always have risk in accepting that the result is true or accepting drawn results of inference . this risk can be minimized but can not be eliminated.

hence benifits of application of statistics in face of uncertainty is that it is used to make a idea about future results , in thus case we can prepare ourself to be ready for upcoming problems . it also used for prediction about future values ,for example in stock market we predict future values of stocks by inference .

and disadvantage is that there is always some uncertainty in results drawn from inference .

Hypothesis Testing Directions: You will conduct your own hypothesis test. Find something you think is interesting and contains a proportion that you would like to test. You need to conduct a left, right or two-tailed hypothesis test based on whether or not you believe this statistic to be too low, too high or just plain wrong. You will need to state your hypothesis, determine the minimum necessary sample size, perform calculations, and present your results in a short paper. Use...
