A local bank claims that the waiting time for its customers to be served is the lowest in the area. A competitor bank checks the waiting times at both banks. The sample statistics are listed below. Test the local bank’s claim. Use the information given below. Use a significance level of .05 and assume the variances are equal. Sample statistics for a local bank and a competitor's bank Sample size Local Bank n1=46 Competitor Bank n2=50 Average waiting time in minutes for each sample X¯¯¯1=2.3 mins. X2__ =2.6 Sample Standard Deviation of each Sample s1= 1.1 mins s2=1.0 mins. Are the samples dependent or independent? State your Null/Alternative hypotheses What is the test-statistic?
