podryga [215]

Answer:

-0.46

Step-by-step explanation:

We have small sample sizes n1 = 9 and n2 = 9. $\bar{x}_{1} = 85.11$ , $\bar{x}_{2} = 86.56$ ; $s_{1} = 7.47$ , $s_{2} = 5.75$ .

$s_{p}^{2} = \frac{(n_{1}-1)s_{1}^{2}+(n_{2}-1)s_{2}^{2}}{n_{1}+n_{2}-2} = \frac{(9-1)(7.47)^{2}+(9-1)(5.75)^{2}}{9+9-2} = 44.43$

Because Carlos conducts a study comparing the performance of individuals on the first quiz in each of two classes taken in the first term of their freshman year, the hypothesis null is $H_{0}: \mu_{1}-\mu_{2} = 0$ , then, the observed t-value is

$t=\frac{(\bar{x}_{1}-\bar{x}_{2})-0}{s{p}\sqrt{1/n1+1/n2}} = \frac{-1.45}{6.67(0.47)} = -0.46$
