The statement that is not true about the data is statement D.

Step-by-step explanation:

The higher value is 78 and the lower value is 12. In order to find the range, we must subtract these two.

78 - 12 = 66

The range of the sales is 66 bars, so A is correct.

The upper quartile is 48 and the lower quartile is 24. To find the interquartile range, we have to subtract them.

48 - 24 = 24

The interquartile range of the data is 24, so B is correct.

The first quartile, or lower quartile, of the data is 24 bars, so C is correct aswell.

Lastly, the third quartile of the data is 48 bars, so D is not true, it is incorrect.

I moved the answer here for more convenience.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
