Sagot :

To determine the number of defective units of Children's Accessories, we can follow these steps:

1. Find the total number of units of Children's Accessories.
2. Identify the percentage of Accessories that are defective.
3. Calculate the actual number of defective units by applying the percentage to the total number of units.

First, we know from the provided table that the total number of Children's Accessories is 1,237.

Next, we see that the percentage of defective units (Accessories) is given as 0.4%.

To find the actual number of defective units, we calculate:

[tex]\[ \text{Defective Units} = \text{Total Units} \times \left( \frac{\text{Percentage of Defective Units}}{100} \right) \][/tex]

Plugging in the values:

[tex]\[ \text{Defective Units} = 1,237 \times \left( \frac{0.4}{100} \right) \][/tex]

[tex]\[ \text{Defective Units} = 1,237 \times 0.004 \][/tex]

[tex]\[ \text{Defective Units} \approx 4.948 \][/tex]

Since the number of defective units must be an integer, we round 4.948 to the nearest whole number, which is 5.

Therefore, approximately 5 units of Children's Accessories were found to be defective. However, since the options provided in the question are not precise with respect to the calculation, the closest match from the options given would be none of the listed options (A, B, or C). A re-evaluation of the options or additional information would be required to better align the calculated answer with the provided choices, which appear to include a systematic error or an oversight in accuracy or interpretation of defective unit thresholds.
