x2 =  -0.600000

x3 = -0.521600

Step-by-step explanation:

Given the formula;

xn+1 = (xn)³-5/10

x2 = (x1)³-5/10

Given x1 = -1

x2 = (-1)³-5/10

x2 = (-1-5)/10

x2 = -6/10

x2 = -0.600000

x3 = (x3)³-5/10

Given x3 = -0.6

x3 = (-0.6)³-5/10

x3 = (-0.216-5)/10

x3 = -5.216/10

x3 = -0.521600

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.
