(Hint: See Example 3.9.) lower quartile upper quartile mg/slice mg/slice mg/slice interquartile range Interpret the values of the quartiles and the interquartile range (in mg/slice). (Hint: See Example 3.9.) Twenty-five percent of the cheese pizzas have sodium contents lower than higher than value of mg/slice while seventy-five percent of the cheese pizzas have sodium contents mg/slice tells us that fifty percent of the cheese pizzas have sodium contents between a lower mg/slice.

Explanation / Answer

218   402   440   441   459   541   565   625   650   658   676   677   708   

So, the bottom half is

218   402   440   441   459   541   

Lower quartile

The median of these numbers is 440.5.

So, the upper half is

625   650   658   676   677   708   

upper quartile

The median of these numbers is 667.

The interquartile range is the difference between the third and first quartiles.

The upper quartile is 667.

The lower quartile is 440.5.

The interquartile range = 667 - 440.5 = 226.5.

Twenty five percent of the cheese pizzas lower than 440.5 mg/slice seventy five percent of the cheese pizzas have sodium contents higher than 667 mg/slice.

The interquartile range of 226.5 mg/slice tells us the fifty percent of the cheese pizzas have sodium contents between the lower value of 440.5 and higher than 667 mg/slice
