What is the probability that a value falls in the interval μ ± 3σ, that is compute the probability P(-3 < Z < 3). Round to four decimals and use leading zeros. (Be sure to write down this answer - you will need it again.)

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.
