eh mi baso solo sul grafico però sull'80 sono abbastanza sicuro

il IV.1 ok

il IV.2 uso la E(|X*|^3)/sqrt n; tu cosa hai usato scusa?

se tu guardi il Grafico b vedi che la funzione va a 1 quando arriva a 80 esattamente come nel grafico II.3 quando a 3 va a uno e infatti la n lì vale 3...mentre per la p ti basi sul terzo grafico suppongo

anche io per la IV.3 ho isolato la n e mi esce uguale a (p^2 + q^2)^2/(E sqrt(pq))^2

e nel IV.4 n quanto vi esce?

per il III.1 avete guardato solo i grafici?

scusate ancora ma l'esercizio IV.1 oscar hai detto di confrontare il 0.53766 coi 2 valori trovati sulle tavole ma nel testo cè scritto che il 0.53766 lo ha trovato con n=100 e p=0.7 mentre ci chiede l'approssimazione per n e p di III.1!!!!!!

anche a me IV.4 esce 1,6 * 10^8, quindi 160 * 10^6, cioè qualche milione.

ho sostituito p = 0,7 e epsilon = 10^-4

confermo 160 milioni

ma l'esercizio IV.1 hai detto di confrontare il 0.53766 coi 2 valori trovati sulle tavole ma nel testo cè scritto che il 0.53766 lo ha trovato con n=100 e p=0.7 mentre ci chiede l'approssimazione per n e p di III.1!!!!!!

ergo i valori del III.1 sono per forza 100 e 0.7???
