Final answer:
The essential details such as sample size, sample mean, and standard deviation are missing to calculate the margin of error for the mean weight of newborn girls. Without this information, it is not possible to provide the correct answer from the given options.
Step-by-step explanation:
The question appears to be asking for the margin of error for the mean weight of newborn girls at a 90% confidence level. Nevertheless, it lacks the necessary sample size, sample mean, and sample standard deviation data needed to calculate the margin of error.
These values are essential when using the formula for the margin of error, which is ME = z*(σ/√n), where z is the z-score corresponding to the confidence level, σ is the standard deviation, and n is the sample size. Without this information, it's impossible to determine the margin of error from the options given.
