SECINĀJUMI:
Grāmatu eksemplāru skaits 2006. un 2007. gadā ir dažāds.
Pazīmes neatbilst normalājam sadalījumam, tāpēc tiek pielietots Vilkoksona tests.
Sakarību starp pazīmēm pārbauda ar Pīrsona Korelācijas koeficientu. Gala rezultātā: netiek noraidīta nulles hipotēze ar vārbūtību 0, 99, un tiek noteikta cieša, negatīva sakarība (-0, 970 > 0, 8)
Izdoto grāmatu skaits 2006. un 2007. gadā nav vienāds (Vilkoksona tests, noraida H0 ar P 0, 95).
