i need help for this subject...
1.scores on the first two sets of statistics tests you took were normally distributed and reported means of 90 for Test A and 50 for Test B.
a. would you hope for a high or a low standard deviation for Test A? Why? Draw a graph illustrating
the logic in your responses.
b. would you want a high or low standard deviation for Test B if you feel that you did well on
the test? Why? Draw a graph illustrating the logic in your responses
2.employees at the Kansas City plant average 42.2 units of output per hour with a standard
deviation of 10.2 units. The same values for the Denver plant are 41.7 and 12.7
a.which employees are more consistent in their production pattern?
b.which might have the more productive employees if output is normally distributed?
NOTE...Please help me to solve me this problem, I do appreciate it,,,Thanks to all..
