Be prepared to identify:

-Basic statistical calculations (i.e. central tendency and variation) 

-The distribution (shape / skew) of the data

-Inferences about the sampling frame

-An ability to test a hypothesis related to the presented data

                                        

 

Assuming that each deposit recorded in the data matrix reflects the amount of money an individual student is able to save per month ……   to accept the hypothesis that – at a .005 level of confidence – the majority of students are able to save more than $150 per month [ i.e.:  H0:  μ = 150   /  HA: μ > 150] would be: ­­­­________
