A LEER: ​   No se sabe exactamente…​

Suppose a company has decided that both X-bar and R-charts should be maintained on a certain quality aspect. At 12 different points in time, a sample of six units was taken.  The total of all 12 sample averages was 96, and the total of all 12 sample ranges was 30.  The initial (trial) upper control limit for the X-bar chart would be

Suppose you had an X-bar chart and an R-chart for some quality aspect, as follows. The center line for the X-bar chart was 20, the upper control limit was 21.8, and the lower control limit was 18.2. The center line for the R-chart was 2.  The sample size is 7.  A quick and dirty estimate of the natural tolerances would be

In a particular species of mice, the yellow coat color is dominant to black coat color, but the homozygous dominant genotype results in embryonic lethality. When two yellow mice are mated, what proportion of their litter of baby mice will have yellow coat colors?

A form of Rickets is due to an X-linked dominant allele. Alice does not have Rickets, but her spouse Walter does have Rickets. What is the percent chance that their next child will be a daughter with Rickets? 

A DTC result indicates that I have a 12% overall risk for osteoporosis based on my having a SNP that accounts for a 3% relative risk for osteoporosis. What is the general population risk for osteoporosis?
