l'emofilia è una malattia ereditaria determinata dalla presenza di un gene recessivo (X*) localizzato sul
cromosoma sessuale X.
a) Calcola la probabilità che da una coppia di genitori formata da una madre portatrice sana (X*X) e
dal padre sano (XY)possa nascere una figlia portatrice sana. Utilizza una tabella a doppia entrata.
Esprimi la probabilità in percentuale.
b) Dall'unione di una madre sana (XX)e un padre emofiliaco (X*Y), qual è la probabilità che nasca un
figlio maschio sano? E un maschio malato? Esprimi la probabilità in percentuale.

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
