Seven college students are asked how many social media platforms they visit frequently. The observations (in number of platforms) are 1,2,2,2,2,3 and 4 . Find the percentile of the observation 3 platforms. The percentle of the observation 3 platforms is square . (Round to the nearest integer as needed.) Please copy and paste data from text area below. Selected delimiter: Space square

To find the percentile of the observation 3 platforms, we first need to determine how many observations are less than 3.<br /><br />The given data is: 1, 2, 2, 2, 2, 3, 4<br /><br />There are 5 observations (1, 2, 2, 2, 2) that are less than 3.<br /><br />The formula for calculating the percentile rank of a value is:<br /><br />\[<br />\text{Percentile} = \left( \frac{\text{Number of values below } x}{\text{Total number of values}} \right) \times 100<br />\]<br /><br />Plugging in the numbers:<br /><br />\[<br />\text{Percentile} = \left( \frac{5}{7} \right) \times 100 \approx 71.43<br />\]<br /><br />Rounding to the nearest integer, the percentile of the observation 3 platforms is 71.
