Assuming that the tobacco company’s claim is true‚ what is the probability that the mean tar content of the sample is greater than 4.15 milligrams? [0.00621] 2.

precision can be made using the results. Precision refers to how close a set of results are to each other. In this lab‚ the percent relative average deviation can be used as an indicator of preciseness. Percent relative average deviation is a measure of how tightly clustered a set of data points is around a mean. A low percent relative average deviation indicates that the data points are tightly clustered around the mean; moreover‚ if the

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 to see
