In a factory manufacturing electronic components there are four machine operators and fivemachines producing similar items. The quality of the components having been quite variable,an experiment was conducted to determine whether the variability was caused by differencesbetween machines, differences between operators or both. The production was observed foreach shift, with each operator using each of the five machines for a whole shift. The quality ofthe components produced during any shift was assessed by quality control inspectors on a scaleof 0 to 100, with 100 corresponding to perfect quality and 0 to useless material. The resultswere as given in the following table.MachineOperatorABCDE156 92 53 93 6826483 55 95 6262362 80 56 96451 78 44 88 69Carry out an appropriate analysis of variance, and test for differences between operators andbetween machines.

A researcher wants to investigate whether single people who own pets are happier than singles without pets. A mood inventory is administered to a group of 20-29 years old non-pet owners and a similar age group of pet owners. The pet owners are also matched one one one with non-pet owners for income, number of close friends, and general health. The data are as follows: Non-pet owner pet owner 10 15 9 9 11 10 11 19 5 17 9 15 is there a significant difference in the mood scores for non-pet owners and pet owners?
The following data give the percentage of women working in five companies in the retail and trade industry. The percentage of management jobs held by women in each company is also shown. % Working 67 45 73 54 61 % Management 50 23 63 47 34 (a) Develop a scatter diagram for these data with the percentage of women working in the company as the independent variable. A scatter diagram has 5 points plotted on it. The horizontal axis ranges from 40 to 75 and is labeled: % Working. The vertical axis ranges from 0 to 70 and is labeled: % Management. The first three points are plotted from left to right in an downward, diagonal direction starting in the upper left corner of the diagram. The fourth point extends upward in a diagonal direction to the right. The last point then extends downward from the fourth point in a diagonal direction to the right. The points are between 23 to 63 on the vertical axis. A scatter diagram has 5 points plotted on it. The horizontal axis ranges…
