For the data given, we have 24 entries in all.

They are :

75, 36, 80, 49, 24, 61, 34, 39, 30, 76, 44, 44, 40, 35, 21, 89, 34, 70, 79, 65, 66, 53, 99, 11

(1) Minimum refers to the lowest data in the table. we can see out of all the data in the table, the lowest is 11. Therefore,

Min = 11

(2) Maximum refers to the highest data in the table.

The highest is 99.

Therefore,

Max = 99

(3) Range is defined as highest data minus lowest data

Range = 99 - 11

Range = 88

(4) Mean:


\begin{gathered} \text{ Mean =}\frac{\text{ sum of the data}}{total\text{ count}} \\ \operatorname{mean}\text{ = }(75+36+80+49+24+61+34+39+30+76+44+44+40+35+21+89+34+70+79+65+66+53+99+11)/(24) \\ \\ \text{Mean = }(1254)/(24) \\ =52.25 \end{gathered}

Therefore,

Mean = 52.25

(5) Standard deviation:

The steps to calculate the standard deviation in shown in the picture below.

The standard deviation = 22.8386..

To 2 decimal places, we have 22.84

Therefore,

Standard deviation = 22.84
