One hundred thirty people were asked to determine how many cups of fruit and water they consumed per day. the results are shown
in the frequency table. a 4-column table with 3 rows. the first column has no label with entries less than or equal to 4 cups of water, greater than 4 cups of water, total. the second column is labeled less than or equal to 2 cups of fruit with entries 62, 18, 80. the third column is labeled greater than 2 cups of fruit with entries 20, 30 , 50. the fourth column is labeled total with entries 82, 48, 130. identify the conditional relative frequency by row. round to the nearest percent. the conditional relative frequency that someone ate more than 2 cups of fruit, given the person drank less than or equal to 4 cups of water is approximately . the conditional relative frequency that someone ate less than or equal to 2 cups of fruit, given the person drank more than 4 cups of water is approximately .
The second purchase is exactly half-again larger than the first purchase, so sheds no light on the relative costs of the items. The per-item costs can be found when the ratio of items purchased is different from one buy to another.
