Solution
Calculate the mean of the hours of training.
Mean Calculation Formula.
The mean μ is calculated using the formula μ=N∑i=1Nxi. For the hours of training, we have μ=621=3.5.
Mean Result.
The mean of the hours of training is 3.5.
3.5
Calculate the variance and standard deviation of the hours of training.
Variance Calculation Formula.
The variance σ2 is calculated using the formula σ2=n∑(xi−μ)2. For the hours of training, the variance is 2.92.
Standard Deviation Calculation.
The standard deviation is calculated as 2.92=1.71.
2.92 and 1.71
Calculate the mean of the order of training.
Mean Calculation Formula.
The mean μ is calculated using the formula μ=N∑i=1Nxi. For the order of training, we have μ=617=2.83.
Mean Result.
The mean of the order of training is 2.83.
2.83
Calculate the variance and standard deviation of the order of training.
Variance Calculation Formula.
The variance σ2 is calculated using the formula σ2=n∑(xi−μ)2. For the order of training, the variance is 2.47.
Standard Deviation Calculation.
The standard deviation is calculated as 2.47=1.57.
2.47 and 1.57
The mean of the hours of training is 3.5. The variance of the hours of training is 2.92 and the standard deviation is 1.71. The mean of the order of training is 2.83. The variance of the order of training is 2.47 and the standard deviation is 1.57.
