The store that has a greater variety of numbers of wristbands sold is the store whose box plot has a greater IQR value.

<h3>How do we Determine Variability in a Box Plot?</h3>
  • Variability of a data distribution that is represented by a box plot can be determined by the interquartile range (IQR) = Upper Quartile (Q3) - Lower Quartile (Q1).
  • See the diagram attached below to understand how to get the Q3 and Q1 of the data distribution.

In conclusion, variability is a measure of IQR. The greater the IQR of a box plot, the greater the variety. Thus, the store that has a greater variety of numbers of wristbands sold is the store whose box plot has a greater IQR value.

Ratling [72]

Answer:

The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate  into 355 mL of water is 0.9881M

Molarity of solution is the ratio of the number of moles of the substance to the volume.

n is the number of moles of the compound

Mass of calcium nitrate = 54.3g

Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
