You are interested in cell size regulation and discover that signaling through a GPCR is important in controlling cell size in rat white blood cells. The G protein downstream of this receptor activates adenylyl cyclase, which ultimately leads to the activation of PKA. You find that cells that lack the GPCR are 15% smaller than normal cells, whereas cells that express a mutant, constitutively activated version of PKA are 15% larger than normal cells. Furthermore, the normal blood cells become...

The average age at which adolescent girls reach their adult height is 16 years. Suppose you have a sample of 29 adolescent girls who are developmentally delayed, and who have an average age at which they reached their adult height of 17.8 years and a sample variance of 77.4 years. You want to test the hypothesis that adolescent girls who are developmentally delayed have a different age at which they reached their adult height than all adolescent girls. Calculate the...
