Om tot een correcte oplossing te komen moest voor deze opgave de R-code aangepast worden. De student heeft dit juist gedaan.
Het teken > werd correct vervangen door < en ook 'more than' werd veranderd naar 'fewer than'.
Tot slot werden ook de Engelse benamingen voor de y en x as van de grafiek vertaald naar het Nederlands.

De student heeft de R-code begrepen en juist aangepast. Het >-teken moest gewijzigd worden in het <-teken. Ook was het nodig om de titels van de assen te vertalen en dat is ook gebeurd.

Student heeft deze vraag goed begrepen en de R code correct aangepast:

plot(bigprob,col=2,main='Waarschijnlijkheid in het grote ziekenhuis',xlab='#simulated days',ylab='probability')
dev.off()

plot(smallprob,col=2,main='Waarschijnlijkheid in het kleine ziekenhuis',xlab='#simulated days',ylab='probability')
dev.off()

dum1 <- paste('#Days per Year when fewer than', par4*100, sep=' ')

dum <- paste(dum1, '% of male births occur in Small Hospital', sep=' ')

Ook hier weer is de oplossing correct, zowel het teken als de tekst is aangepast in de R code.

De student heeft de juiste oplossing gegeven. In de R-Code moest het teken > verandert worden in <, en 'more' moest vervangen worden door 'less'.

De oplossing is correct. De student moest een aanpassing doen van de r-code.
Hierbij moest men 'more then' vervangen door 'less then' en de 'gelijkheidstekens' aanpassen (> wijzigen in <)



2008-10-21 07:41:42 [Joachim Van Hemelen] [reply
De bereking is correct opgelost. Het > is vervangen door <, en 'more' door 'fewer' (less)
