Als we zien naar het run sequence plot, zien we duidelijk dat er geen constante spreiding is, maar wel een dalend verloop. Deze vraag heb ik goed beantwoord.

Het anwoord op vraag 4 kunnen we ook aan de hand van het run sequence plot aflezen. Hier zien we dat we te maken hebben met een seizoenaal patroon, maar deze is wel moeilijk af te lezen op de grafiek. Hiervoor gaan we later een nieuwe methode zien, namelijk deze van het mean plot. Bij Vraag 2, assumptie 1 hebben we ook gezien dat er seizoenaliteit is vanwege de autocorrelatie zie hiervoor naar antwoord op assumptie 1.
