Assuming normality and equal varIance and usmg independent samples with 1/1 = 9, .r = 12
Chapter 25, Problem 25.1.58(choose chapter or problem)
Assuming normality and equal variance and using independent samples with \(n_{1}=9, \bar{x}=12 . s_{x}=2\), \(n_{2}=9, \bar{y}=15, s_{y}=2\), test \(H_{0}: \mu_{x}=\mu_{y}\) against \(\mu_{x} \neq \mu_{y}\); choose \(\alpha=5 \%\).
Text Transcription:
n_{1} = 9, bar{x} = 12 , s_{x} = 2
n_{2} = 9, bar{y} = 15, s_{y} = 2
H_{0}: mu_{x} = mu_y
mu_x neq mu_y
alpha = 5%
