I need help with this question.

(a) The opening of the drinking straw was about 6 mm (millimeter )wide.

(b) The mass of the baseball was about 145 g (gram)

(c) In her shower, Kaitlin used about 110 liter of water.

Step - by - step explanation:

(a) The lengths are measured in mm or cm or m.

Straw opening is small size. So it is measured in mm.

The opening of the drinking straw was about 6 mm (millimeter )wide.

(b) Mass means weight. Weight is usually measured in gram or kg.

Baseball is lower weight. So, it is measured in gram.

The mass of the baseball was about 145 g (gram).

(c) Liquids are measured in milliliter or liter.

Shower has larger quantity of water. So, it is measured in liter.

In her shower, Kaitlin used about 110 liter of water.

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
