balance score decreases by -0.347 average number of hours per week. Next‚ we have to interpret the random error component ( ) of the least squares line. The estimate of error standard deviation for this particular data set is 12.28455 which suggests that the work-life balance score (y) values should be two times of the standard deviation. This can be best expressed as in the equation of 2s = 2(12.28455) which equals 24.57 average hours per week. Then‚ we can analyze the accuracy of hypothesis model

In the pursuit of gold much damage was done to California’s ecosystem. Traditional mining practices‚ such as placer mining and rocker/ cradle mining by individuals and small groups of miners in California did damage the environment in small ways‚ but the real damage began to occur when big groups and conglomerates started diverting rivers to dig the stream bed and using Hydraulic mining equipment. These larger operations with more capital were able to use more mechanized and expensive equipment

step in analysing the data is determining if outliers exists within the data. The presence of outliers must be evaluated because their existence could distort the data and make it inaccurate. In order to determine if outliers exist the average and standard deviation must be calculated in order to calculate the Z score‚ which will show‚ wither or not outliers exist. In this instance to outliers where found present in the data set as all of the data fell within the +3‚-3 range‚ the largest positive outlier
