the j th child in the i th vehicle of the h th region which is equal to the population sizeof the region divided by the actual sample size collected on the variable ofinterest in that particular region.To obtain the national weighted estimates, we combine the provincial estimatesusing weights equal to the national child population size divided by provincialchild population sizes. It is to be noted that both in the regional and provincialweights the child population sizes refer to the regions which have actual samplespresent in the data.The standard errors of the estimates were computed by Taylor expansionmethod and most of the analysis was carried with the help of the PROCSURVMEANS of the SAS software.The provincial as well as national weighted estimates of the correct use based onthe criteria in Tables B, C & D are reported in Tables 3.4.1-3.4.10.Table-3.4.1: National weighted estimates of correct use based on child’sage, actual weight and actual height and on the criteria in Table B.26Proportion Estimate StandardError95% ConfidenceIntervalLower UpperNational 59.6% 60.18% 1.92% 56.41% 63.95%Table-3.4.2: Provincial weighted estimates of correct use based on child’sage, actual weight and actual height and on the criteria in Table B.Province Proportion Estimate StandardError95% ConfidenceIntervalLower UpperAlberta 62.5% 59.19% 5.72% 47.89% 70.49%BritishColumbia56.8% 64.66% 5.12% 54.54% 74.77%Manitoba 52.1% 58.34% 12.08% 33.74% 82.94%NewBrunswick65.4% 64.38% 4.26% 55.96% 72.79%Newfoundland 60.2% 56.75% 6.32% 44.17% 69.33%Nova Scotia 57.7% 63.78% 8.47% 47.00% 80.55%NorthwestTerritories36.8% 36.84% 10.47% 13.79% 59.89%Ontario 64.6% 63.43% 2.52% 58.47% 68.39%
