The weightedanalysis is carried out as described in earlier sections. The weighted estimates ofthe correct use rate for the provinces are very close to the un-weighted (unlikethe parking lot data) except perhaps for New Brunswick for which the weightedestimate of correct use rate is about 6% lower than its un-weighted version. Also,for the national estimates, there is 2% difference between weighted and unweightedversions of the correct use rates. However, both estimates are withinthe 95% confidence intervals in all cases.Table-3.7.1: National weighted estimates of correct use for the road sidesample .Proportion Estimate StandardError95% ConfidenceIntervalLower UpperNational 58.4% 60.52% 0.62% 59.30% 61.74%32
