... Since Z lies in the rejection region (as z = 4 exceeds = 1.2816), we reject . Thus, at α = 10% level of significance, the evidence is sufficient to indicate that manager’s assumption is incorrect and that the average number of sales contacts per month exceeds 60. ...

Hypothesis Testing Methods to test
... If the data are from a process (data observed over time, referred to as time-series data in the text), first check to assure that the process has stable characteristics. Do not attempt statistical inference for a process with unstable characteristics. Identify the unknown parameter (either proportio ...

... no short-hand notation is used that is acceptable (for example P(Group B and passed)). The definition of shorthand notation can be found anywhere on the page (for example if a student defines P in Question 3 and uses it again for Question 4 that is acceptable). The short-hand notation of B and P are ...

Measurement and Uncertainty
... A histogram is a bar graph that indicates how often a measurement falls within a particular range of values. On the abscissa (x-axis) the range of all possible measured values is subdivided into smaller intervals termed “bins”. The ordinate (y-axis or height of each of the bars) gives the number of ...
