Four Types of Bicycle Tires Are Ridden in Six Different $\chi$

Four types of bicycle tires are ridden in six different cities to see if the tires lasted about the same number of miles.If there are differences, then that tire could promote its durability to potential customers.Using the data in the table below and an alpha of 0.05, what is the observed value of $\chi$ ²? $$\begin{array} { l c c c c } & \text { Tire A } & \text { Tire B } & \text { Tire C } & \text { Tire D } \\\text { City 1 } & 105 & 157 & 112 & 119 \\\text { City 2 } & 142 & 124 & 132 & 144 \\\text { City 3 } & 133 & 121 & 138 & 130 \\\text { City 4 } & 98 & 136 & 110 & 119 \\\text { City 5 } & 114 & 141 & 95 & 128 \\\text { City 6 } & 117 & 138 & 129 & 140\end{array}$$
