Hoffman, Jabaay, and Leuer did a study of pencil lead strength. They loaded pieces of lead of the same diameter (supported on two ends) in their centers and recorded the forces at which they failed. Part of their data are given here (in grams of load applied at failure). 4H Lead:56.7, 63.8, 56.7, 63.8, 49.6
H Lead:99.2, 99.2, 92.1, 106.0, 99.2
B Lead: 56.7, 63.8, 70.9, 63.8, 70.9
A) In applying the methods of this chapter in the analysis of these data, what model assumptions must be made? Make three normal plots of these samples on the same set of axes and also make a normal plot of residuals for the one-way model as means of investigating the reasonableness of these assumptions. Comment on the plots.
B) Compute a pooled estimate of variance based on these three samples. What is the corresponding value of sp?

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
