Be prepared to identify:
-Basic statistical calculations (i.e. central tendency and variation)Â
-The distribution (shape / skew) of the data
-Inferences about the sampling frame
-An ability to test a hypothesis related to the presented data
                                       Â
Â
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: ÂÂÂÂ________
