W s0% confidencet can be said that the population mean epar cost i beteen the bounds of the confidence interval OC Ha large sample of moble devices are taken approximately s0% of them wit have repair ocosts beteeen the bounds of the confidence interval OD Win 90% confidence it can be said that the repair cost is between the bounds of the confdence iterval
