In order to investigate the relationship between mean job tenure in years among workers who have a bachelor s degree or higher and those who do not, random samples of each type of worker were taken. Sample 1 had mean value of 8.2, standard deviation of 1.3 and a sample size of 155. Sample 2 had mean value of 7.0, standard deviation of 1.5 and a sample size of 210. Construct the 90% confidence interval for the difference in the population means based on these data. "0.9506 to 1,4493" 0.9506 to 1.5593 0.8756 to 1.4493 0.1234 to 0.4321 0.7506 to 1.4493
