Extracted text: 5. Astudent wanted to determine whether the wait time in the drive through at McDonald's differed from that at Jollibee's. She used a random sample of 30 cars at McDonald's and 27 cars at Jollibee and obtained these results (in seconds): Wait Time at McDonalds Wait Time at Jollibee 51.09 126.62 101.03 281.9 174.43 110.55 191.6 147.28 71.37 187.53 119.61 182.54 141.78 111.84 131.69 196.84 204.29 390.5 122.06 137.9 86.31 284.48 190.91 386.71 140.44 121.21 128.75 123.66 171.01 133.56 115.66 100.04 246.59 203.62 270.82 110.64 227.38 116.72 95.09 71.02 385.9 183.79 126.91 81.43 153.34 199.86 128.59 127.35 131.21 100.94 233.65 471.62 122.62 195.44 156.34 363.34 155.53 a) Is there a difference in wait times at each restaurant's drive-through? Use 0.1 level of significance. b) Create a graph to compare the two data sets. Ensure that the graph shows visual evidence that support the results that you obtained in (a).
