Interpret the results found in the previous parts. Do the confidence intervals suggest a difference in the variation among waiting times? Does the single-line system or the multiple-line system seem to be a better arrangement?
O A. The variation appears to be significantly lower with a single line system. The multiple-line system appears to be better.
O B. The variation appears to be significantly lower with a multiple-line system. The single-line system appears to be better.
O c. The variation appears to be significantly lower with a multiple-line system. The multiple-line system appears to be better.
O D. The variation appears to be significantly lower with a single line system. The single-line system appears to be better.
