SHIFT 2: 18 25 56 42 29 38 54 47 35 30. SHIFT 2: 23 19 50 49 67 34 30 59 40 33. SHIFT 3: 19 22 24 40 45 29 33 29 39 59. SHIFT 4:
21 23 25 40 35 19 70 40 22 23. The summary statistics for all of the workers at a steel factory are shown. Four sample groups were taken from each of the four shifts. For which sample group is the mean closest to the population mean?
1 answer:
To answer this question you will need to calculate the mean for each of the Shifts and then compare those means to the mean of all the data given. I have attached a picture of the means for each shift and the population mean (all the data).
Shift 1 is the closest to the population mean. It is 37.4, and the population mean is 35.9.
Shift 1 is the closest to the population mean. It is 37.4, and the population mean is 35.9.

Answer:
Step-by-step explanation:
The maximum number of turning points in a cubic function is 2.
In this case,
The discriminant is
, which means the derivative has no real roots. This means there are no critical points and thus no turning points/relative extrema.
In this case,
The discriminant is
