... To do this, we have already calculated confidence intervals for them, now we will be conducting hypothesis tests about the populations parameters of interest. We will discuss these two statistical procedures, in general they are built on the idea that if some theory about the population parameters i ...

... a) Each person will be assigned a number using a random number generator. The names of the people will then be listed, in numerical order (their assigned number) from smallest to greatest. The first 50 people will be group A (the new repellent) and the last 50 will be group B (the current compound). ...

... tests have well known normed values; for instance, most intelligence tests are normed to a mean of 100 and standard deviation of 15. These values are often treated as if they are population parameters, μ and σ, respectively. Assumptions Random sampling σ1 =σ2 Population standard deviations or va ...
