5b)

Answer 1

Solution4:

from boxplot we see

the median line(cent er lines) are different

the group means of main,satellite1,satellite2 ,satellite 3 are different.

we can conduct One way ANOVA

to check if the 4 group means are statistically significant.

there is an outlier seen from main group

highest median value is observed for main group and

least for satellite 1.

Solution5a:

80% of the defects found from 20% of the items is par e t o chart

the curve meets for 80% on curve ,20% is at fabric flaws

that is 80% of the defects are from fabric flaws,we should have control or check point on fabric flaws

Solution5b:

80% of the defects found from 20% of the items is pa re to  chart

the curve meets for 80% on curve ,20% is at loose thread

so 80% of the defects are from loose thread .we should have control or check point on loose thread.
