A study was conducted that investigated the gene ACTN3, which encodes a protein that functions in fast-twitch muscle fibres. People can be classified according to which genotype of this gene they have, RR, RX or XX. The study included a sample of elite sprinters and a sample of endurance athletes. The researchers are investigating whether there is an association between the genotype classification and the type of athlete (sprinters or endurance). The table below displays the data observed in the study. Under an assumption of no association between genotype and type of athlete, what would be the expected number of people in the Sprinters and XX category? (give your answer to 2 decimal places) Observed counts XX RX RR Total Endurance 55 49 30 134 Sprinters 49 95 50 194 Total
