Question

2 tables. A 4-column table with 3 rows is titled Frequency Two-way table. Column 1 has entries boys, girls, total. Column 2 is labeled 4-year with entries 76, 83, 159. Column 3 is labeled 2-year with entries 34, 38, 72. Column 4 is labeled total with entries 110, 121, 231.A 4-column table with 2 rows titled Relative frequency table by rows. Column 1 has entries boys, girls. Column 2 is labeled 4-year with entries a, c. Column 3 is labeled 2-year with entries b, d. Column 4 is labeled Total with entries 100 percent, 100 percent.

Answer 2

Answer: The values are as follows; a = 69%, b = 31%, c = 69%, d = 31%

Step-by-step explanation: Please see the attached picture for more details. The question gives a set of values in a frequency two-way table. The table has rows and columns depicting values that are related. In the first row labelled boys, for the 4-year column you have 76 and for the 2-year column you have 34 totaling 110. However, the total row is now labelled 100%, which means the two values under the "Boys" row have relative frequencies calculated as follows;

(A)

Relative frequency for 4-year (a) = (4-year/total) *100

Relative frequency for 4-year (a) = (76/110)*100

Relative frequency for 4-year (a) = 69%

(B)

Relative frequency for 2-year (b) = (2-year/total)*100

Relative frequency for 2-year (b) = (34/110)*100

Relative frequency for 2-year (b) = 31%

(C)

Relative frequency for 4-year (c) = (4-year/total)*100

Relative frequency for 4-year (c) = (83/121)*100

Relative frequency for 4-year (c) = 69%

(D)

Relative frequency for 2-year (d) = (2-year/total)*100

Relative frequency for 2-year (d) = (38/121)*100

Relative frequency for 2-year (d) = 31%
