Answer:

The mean temperature for May is higher than September's mean.

Answer:

The mean temperature of May is higher than the mean temperature of September.

Step-by-step explanation:

The mean is calculated from the box-plot as follows:

It is the ratio of Sum of (Least value, greatest value, Lower quartile i.e. [tex]Q_1[/tex] , Median i.e. [tex]Q_2[/tex] and Upper quartile i.e. [tex]Q_3[/tex] ) to the number of points i.e. 5.

  • Hence, From the Box plot of May we have:

     Least value=52

        Greatest value=79

        Lower quartile or first quartile i.e. [tex]Q_1[/tex]=63

      Middle quartile or Median i.e. [tex]Q_2[/tex]=71

        Upper quartile or Third quartile i.e. [tex]Q_3[/tex]=73

     [tex]Mean=\dfrac{52+63+71+73+79}{5}\\\\\\Mean=67.6[/tex]

  • Hence, From the Box plot of September  we have:

       Least value=47

       Greatest value=88.5

       Lower quartile or first quartile i.e. [tex]Q_1[/tex]=52

       Middle quartile or Median i.e. [tex]Q_2[/tex]=62

       Upper quartile or Third quartile i.e. [tex]Q_3[/tex]=77.5

    [tex]Mean=\dfrac{47+88.5+52+62+77.5}{5}\\\\\\Mean=65.4[/tex]

Hence, the mean of May is higher as compared to September.
