Chapter 6, Problem 2E

(choose chapter or problem)

A random sample of size 29 from a normal distribution has variance $s^2=24$. Test $H_0:\sigma^2 \geq 30$ versus $H_1:\sigma^2<30$.

Equation Transcription:

${s}^{2}=24$

${H}_{0}:{\sigma{}}^{2}\geq{}30$

${H}_{1}:{\sigma{}}^{2}<30$

Text Transcription:

s^2=24

H_0:sigma^2{>\=}30

H_1:sigma^2<30

Image text transcription: A random sample of size 29 from a normal distribution has variance s2 = 24. Test H0 : σ2 ≥ 30 versus H1 : σ2 < 30.
