Question

Given the following information, calculate $s_p^2$, the pooled sample variance that should be used in the pooled-variance $t$ test. $s_1^2 = 4$ $s_2^2 = 6$ $n_1 = 16$ $n_2 = 25$ $\circ s_p^2 = 5.23$ $\circ s_p^2 = 4.00$ $\circ s_p^2 = 6.00$ $\circ s_p^2 = 5.00$

          Given the following information, calculate $s_p^2$, the pooled sample variance that should be used in the pooled-variance $t$ test.
$s_1^2 = 4$  $s_2^2 = 6$
$n_1 = 16$  $n_2 = 25$
$\circ s_p^2 = 5.23$
$\circ s_p^2 = 4.00$
$\circ s_p^2 = 6.00$
$\circ s_p^2 = 5.00$

Given the following information, calculate sp^2, the pooled sample variance that should be used in the pooled-variance t test.
s1^2 = 4 s2^2 = 6
n1 = 16 n2 = 25
∘ sp^2 = 5.23
∘ sp^2 = 4.00
∘ sp^2 = 6.00
∘ sp^2 = 5.00
