A regional manager wants to know if there is a difference between the mean amounts of time that customers wait in line at the drive-through window for the three stor in her region. She randomly samples the wait times at each store. Her data are given in the following table. Use a one-way ANOVA test to determine if there is a differen between the mean wait times for the three stores, at the 0.05 level of significance. Assume the population distributions are approximately normal with equal population variances. Store 1 2.78 2.73 2.83 2.76 3.35 Drive-Through Wait Times (in Minutes) Store 2 2.99 2.92 2.75 3.33 2.75 Store 3 3.53 2.82 3.19 3.41 3.52

2. Interpret this data. 

A regional manager wants to know if there is a difference between the mean amounts of time that customers wait in line at the drive-through window for the three stores
in her region. She randomly samples the wait times at each store. Her data are given in the following table. Use a one-way ANOVA test to determine if there is a difference
between the mean wait times for the three stores, at the 0.05 level of significance. Assume the population distributions are approximately normal with equal population
variances.
