Perform the Indicated Hypothesis Test $$\sigma _ { 1 } ^ { 2 } > \sigma _{ 2 }^ { 2 }$$

question 78

Essay

Perform the indicated hypothesis test. Be sure to do the following: identify the claim and state the null and alternative
hypotheses. Determine the critical value and rejection region. Calculate the test statistic. Decide to reject or to fail to
reject the null hypothesis and interpret the decision in the context of the original claim. Assume that the samples are
independent and that each population has a normal distribution.
-Test the claim that $$\sigma _ { 1 } ^ { 2 } > \sigma _{ 2 }^ { 2 }$$ Two samples are randomly selected from populations that are normal. The
sample statistics are given below. Use $$\alpha = 0.01 .$$ $$\begin{array} { l l } \mathrm { n } _ { 1 } = 16 & \mathrm { n } _ { 2 } = 13 \\\\\mathrm {~s} _ { 1 } ^ { 2 } = 3200 & \mathrm {~s} _ { 2 } ^ { 2 } = 1250\end{array}$$

Definitions:

Accretionary Prism

A wedge-shaped mass of sediment and rock scraped off the top of a downgoing tectonic plate and accreted onto the overriding plate at a convergent plate boundary.

Fold and Thrust Belt

A region in the earth's crust where the rocks have been deformed by horizontal compression, leading to the formation of folds and thrust faults.

Anticlines

Upwardly convex folds in rock layers, typically formed through compression within the Earth's crust.

Synclines

Downward-curving folds in sedimentary strata, opposite of anticlines, which can also be indicators of oil and gas deposits.
