For the Following Data, Compute the Test Statistic and the Critical

question 68

Multiple Choice

For the following data, compute the test statistic and the critical value, and determine whether to reject $H _ { 0 }$ at the $\alpha = 0.10$ level.
$\begin{array} { l | l | l | l | l | l | l | l | l } \text { Sample A } & 42 & 55 & 59 & 57 & 49 & 60 & 43 & 54 \\\hline \text { Sample B } & 28 & 44 & 42 & 64 & 61 & 46 & 39 & 63\end{array}$

• A) S=10 , Critical value is 6, Do not reject \(H _ { 0 }\)
• B) S=10 , Critical value is 6, Reject \(H _ { 0 }\)
• C) S=11 , Critical value is 4 , Do not reject \(H _ { 0 }\)
• D) S=11 , Critical value is 4 , Reject \(H _ { 0 }\)

Definitions:

Approach Shore

The action or process of coming closer to the shoreline or coast.

Wave Base

The maximum depth in a body of water at which wave action can move sediments on the seabed, typically correlating with half the wavelength of surface waves.

Moving Current

A steady flow of a fluid in a particular direction, especially a natural flow of water in the ocean.

Longshore Current

A current, generally in an ocean or large lake, flowing more or less parallel to a coastline.
