Answer 1

(first part) right choice is B.

"От HA: There s a rear relationship between Tamer ture and Crawing Age, p1-0

(second part) t=-5.0506 and p-value=0.000 (9.86E-05)

(third part) right choice is C.

О с. Reject H2. These data d2 not prDV de encence of pchte Incar relation:hip between Temperatur and Crawing Age

since p-value is less than alpha=0.05

(fourth) right choice is B.
