The body temperatures of two species of geckos were measured. The ng 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.

Transcribed Image Text:The body temperatures of two species of geckos were measured. The n1
14 geckos from species A hada mean noon temperature of = 32.66°C
and a standard deviation of s1 =0.81°C, whereas the n = 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 andt critical values?
O Calculated = 8.04; Critical =2.776
%3D
O Calculated = 8.04; Critical = 2.069
O Calculated = 7.46; Critical = 2.093
O Calculated = 7,46; Critical = 2.776
