Define the population parameter, the appropriate test statistic formula, and if the hypothesis test is left-tailed, right-tailed, or two-tailed. Be sure to set up your hypotheses, too. How did you decide on constructing these hypotheses? What level of significance would you use? Why?

Alternative Hypotheses DF6

Description

Share with your peers the null and alternative hypotheses for a decision that is relevant to your life. This can be a personal item or something at work.

Define the population parameter, the appropriate test statistic formula, and if the hypothesis test is left-tailed, right-tailed, or two-tailed. Be sure to set up your hypotheses, too. How did you decide on constructing these hypotheses? What level of significance would you use? Why?

The population parameters that you should use for this discussion are:

μ: the population mean

Example

The term population mean, which is the average score of the population on a given variable, is represented by: μ = ( Σ Xi ) / N. The symbol ‘μ’ represents the population mean. The symbol ‘Σ Xi’ represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on.
