Grand Strand Family Medical Center treats minor medical emergencies for visitors to the Myrtle Beach area. There are two facilities, one in the Little River Area and the other in Murrells Inlet. The Quality Assurance Department wishes to compare the mean waiting time for patients at the two locations. Samples of the waiting times for each location, reported in minutes, follow: Location Waiting Time Little River 31.73 28.77 29.53 22.08 29.47 18.60 32.94 25.18 29.82 26.49 Murrells Inlet 22.93 23.92 26.92 27.20 26.44 25.62 30.61 29.44 23.09 23.10 26.69 22.31 Assume the population standard deviations are not the same. At the 0.05 significance level, is there a difference in the mean waiting time? Click here for the Excel Data File Find the degrees of freedom for unequal variance test. (Round down your answer to the nearest whole number.) State the decision rule for 0.05 significance level: H0: μLitttle River = μMurrells Inlet; H1: μLitttle River ≠ μMurrells Inlet. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places for both answers) Compute the value of the test statistic. (Round your answer to 2 decimal places.)

Question
Grand Strand Family Medical Center treats minor medical emergencies for visitors to the Myrtle Beach area. There are two facilities, one in the Little River Area and the other in Murrells Inlet. The Quality Assurance Department wishes to compare the mean waiting time for patients at the two locations. Samples of the waiting times for each location, reported in minutes, follow:
| Location | Waiting Time | |||||||||||
| Little River | 31.73 | 28.77 | 29.53 | 22.08 | 29.47 | 18.60 | 32.94 | 25.18 | 29.82 | 26.49 | ||
| Murrells Inlet | 22.93 | 23.92 | 26.92 | 27.20 | 26.44 | 25.62 | 30.61 | 29.44 | 23.09 | 23.10 | 26.69 | 22.31 |
Assume the population standard deviations are not the same. At the 0.05 significance level, is there a difference in the mean waiting time?
