Question 1 of 10
The heights of 200 adults were recorded and divided into two categories.

\begin{tabular}{|l|c|c|c|}
\hline
& [tex]$6^{\prime}$[/tex] or over & Under [tex]$6^{\prime}$[/tex] & Total \\
\hline
Male & 14 & 88 & 102 \\
\hline
Female & 2 & 96 & 98 \\
\hline
Total & 16 & 184 & 200 \\
\hline
\end{tabular}

Which two-way frequency table correctly shows the marginal frequencies?



Answer :

To determine the marginal frequencies for the two-way frequency table, we need to complete the table and summarize the total counts in each category. Here's the step-by-step breakdown:

1. Identify and sum up the counts for males:
- Males 6' or over: 14
- Males under 6': 88

Thus:
- Total males = 14 + 88 = 102

2. Determine the total number of people and use it to find the total number of females:
- Total people = 200
- Total males = 102

Thus:
- Total females = 200 - 102 = 98

3. Identify the count for females 6' or over, and determine the count for females under 6':
- Females 6' or over: 2
- Females under 6' = 98 - 2 = 96

4. Calculate the marginal frequencies:
- Total people 6' or over: Males 6' or over + Females 6' or over = 14 + 2 = 16
- Total people under 6': Males under 6' + Females under 6' = 88 + 96 = 184

Now, we can complete the table and include the marginal frequencies:

[tex]\[ \begin{tabular}{|l|c|c|c|} \hline & $6^{\prime}$ or over & Under $6^{\prime}$ & Total \\ \hline Male & 14 & 88 & 102 \\ \hline Female & 2 & 96 & 98 \\ \hline Total & 16 & 184 & 200 \\ \hline \end{tabular} \][/tex]

This table correctly shows the marginal frequencies for each category.
