Question

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.

≤ 2 cups of fruit> 2 cups of fruittotal
> 4 cups of water183048
total8050130

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 dropdown.
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 dropdown with options 14%, 23%, 38%, 60%.

Explanation:

First Conditional Relative Frequency:

Step1: Identify the row and cell.

For "someone ate more than 2 cups of fruit, given the person drank less than or equal to 4 cups of water", the row is "≤ 4 Cups of Water", and the cell for "> 2 Cups of Fruit" is 20. The total of this row is 82.

Step2: Calculate the conditional relative frequency.

The formula is $\frac{\text{Frequency of > 2 Cups of Fruit and ≤ 4 Cups of Water}}{\text{Total of ≤ 4 Cups of Water row}}$. So, $\frac{20}{82} \approx 0.2439$, which is approximately 24% (but let's check the second part first).

Second Conditional Relative Frequency:

Step1: Identify the row and cell.

For "someone ate less than or equal to 2 cups of fruit, given the person drank more than 4 cups of water", the row is "> 4 Cups of Water", and the cell for "≤ 2 Cups of Fruit" is 18. The total of this row is 48.

Step2: Calculate the conditional relative frequency.

Using the formula $\frac{\text{Frequency of ≤ 2 Cups of Fruit and > 4 Cups of Water}}{\text{Total of > 4 Cups of Water row}}$, we get $\frac{18}{48} = 0.375$, which is 37.5% ≈ 38%.

Now, going back to the first one: $\frac{20}{82} \approx 0.2439 \approx 24\%$, but let's check the options (wait, the first part's options aren't shown, but the second part's options include 38%, which matches our calculation for the second one. Let's re-express:

For the first conditional relative frequency (ate more than 2 cups of fruit, given drank ≤ 4 cups of water):
Number of people who ate >2 cups of fruit and drank ≤4 cups of water: 20
Total number of people who drank ≤4 cups of water: 82
So, $20 \div 82 \approx 0.2439 \approx 24\%$ (but maybe the options have 24% or similar, but since the second part's correct answer is 38% (from 18/48 = 0.375 ≈ 38%)

Answer:

First conditional relative frequency (ate more than 2 cups of fruit, given drank ≤4 cups of water): Approximately 24% (calculation: $\frac{20}{82} \approx 24\%$)
Second conditional relative frequency (ate ≤2 cups of fruit, given drank >4 cups of water): 38% (calculation: $\frac{18}{48} = 0.375 \approx 38\%$)

(Assuming the first part's answer is around 24% and the second is 38%, so for the second dropdown, the answer is 38%.)
