The body temperatures of two species of geckos were measured. The n 14 geckos from species A had a mean noon temperature of 32.66°C and a standard deviation of $1- 0.81°C, whereas the n2 11 geckos from species B yielded mean = 30.12°C noon temperature and s2 0.75°. To test the hypothesis of no difference versus the alternative of a difference in mean noon temperature at the 5 % level of significance, one would need to calculate the t-calculated value. What are the t calculated and t critical values?

Question
The body temperatures of two species of geckos were measured. The n; = 14 geckos
from species A had a mean noon temperature of 32.66°C and a standard deviation of
S1 = 0.81°C, whereas the n2 = 11 geckos from species B yielded mean= 30.12°C
noon temperature and s2 = 0.75°. To test the hypothesis of no difference versus the
alternative of a difference in mean noon temperature at the 5 % level of significance,
one would need to calculate the t-calculated value.
What are the t calculated and t critical values?
O Calculated - 8.04; Critical = 2.069
Calculated - 7.46; Critical = 2.093
O Calculated -7,46; Critical - 2.776
O Calculated - 8.04; Critical - 2.776
