A hospital records that the average patient check-in time is 8585 minutes. An administrator implements an electronic kiosk and suspects that the mean check-in time increases. A random sample of 3030 patients shows a mean check-in time of xˉ=87.4\bar{x}=87.4 minutes and a standard deviation of s=6.2s=6.2 minutes. Test whether the kiosk increases the mean check-in time (use a one-sided test at α=0.05\alpha=0.05).

Problem 62Multiple Choice

A hospital records that the average patient check-in time is $85$ minutes. An administrator implements an electronic kiosk and suspects that the mean check-in time increases. A random sample of $30$ patients shows a mean check-in time of $x ˉ equals 87.4$ minutes and a standard deviation of $s equals 6.2$ minutes. Test whether the kiosk increases the mean check-in time (use a one-sided test at $alpha equals 0.05$ ).

There is sufficient evidence to conclude that the kiosk increases the mean check-in time
