The sample provided has a group of 50 data speeds.

The percentileof a given value involves calculating the ratio of the number of values less than that given value to the total number of values.

The ratio of two values is multiplied by 100 to obtain the percentile. In terms of a mathematical expression, it is written as follows:

$P_x=\frac{Numberofvaluesbelowx}{Totalnumberofvalues}脳100$

Steps to find the percentile value:

• List the values from the smallest to the largest.
• Enumerate the total number of observations.
• Enumerate the number of observations less than 9.6 Mbps.
• Use the formula mentioned above to calculate the percentile.

The percentile corresponding to a data speed of 9.6 Mbps is as follows:

$$\begin{gathered} P_{9.6}=\frac{Numberofvaluesbelow9.6}{Totalnumberofvalues}脳100 \\ =\frac{43}{50}脳100 \\ =86 \end{gathered}$$

Therefore, 9.6 Mbps corresponds to the 86^th percentile.
