Final answer:
The question does not provide enough information to calculate the proportion of female applicants hired for the job as a kitchen worker.
Step-by-step explanation:
To determine the proportion of female applicants hired for a job as a kitchen worker, you need to divide the number of females hired by the total number of female applicants. Unfortunately, the question does not provide this information, so we cannot calculate the exact proportion. Therefore, none of the options a) 0.100, b) 0.375, c) 0.400, or d) 0.625 can be confirmed as the correct answer.
