question 35

Short Answer

Draw Dot Plots
-The heights (in inches) of 30 mechanics are listed below. Construct a dot plot for the data. $\begin{array} { l l l l l l l l l l } 70 & 72 & 71 & 70 & 69 & 73 & 69 & 68 & 70 & 71 \end{array}$
$\begin{array} { l l l l l l l l l l } 67 & 71 & 70 & 74 & 69 & 68 & 71 & 71 & 71 & 72 \end{array}$
$\begin{array} { l l l l l l l l l l } 69 & 71 & 68 & 67 & 73 & 74 & 70 & 71 & 69 & 68 \end{array}$

Definitions:

Chi-square Statistic

A statistical measure used to assess the differences between observed and expected frequencies in one or more categories.

Expected Frequencies

In statistics, these are the counts predicted by a hypothesis test for categories in a contingency table, based on the distribution assumptions of the test.

Chi-square Statistic

The Chi-square statistic is a measure used in statistics to compare observed data with data expected under a specific hypothesis, often used in tests of independence.

Expected Frequencies

Predicted counts of occurrences across different categories based on a statistical model.
