Use the following cell phone airport data speeds​ (Mbps) from a particular network. Find the percentile corresponding to the dat
Tems11 [23]

Answer:

Thus percentile lies between 53.3% and 55.6 %

Step-by-step explanation:

First we arrange the data in ascending order . Then find the number of the values corresponding to the given value. Then equate it with the number of observations and x and then multiply it to get the percentile. n= P/100 *N

where n is the ordinal rank of the given value

N is the number of values in ascending order.

The data in ascending order is

0.1 0.2 0.2 0.2 0.3 0.6 0.6 0.6 0.7 0.8 0.8 0.8 0.9 1.3

1.5 1.7 1.9 2.2 2.3 2.3 2.6 2.8 3.3 3.5 5.5 6.1 6.4 6.9 7.5 7.9 8.3 9.8 10.1 11.8 11.9 12.1 12.3 12.7 12.9 13.8 13.8 14.6 14.7 14.8 27.5

Number of observation = 45

4.9 lies between 3.3 and 5.5

x*n = 24 observation x*n = 25 observation

x*45= 24 x*45= 25

x= 0.533 x= 0.556

Thus percentile lies between 53.3% and 55.6 %

Irina18 [472]
Unfortunately, you haven't shared the "figure below" that shows the dimensions of this parcel of land.  Without being able to calculate the area of the parcel, you cannot really answer this question exactly.

Suppose that the area of the parcel were 6000 square meters.  Dividing that by 1500 square meters, we get 4, which represents the number of zebras that can live on this (example) parcel.

Figure out the area of your parcel, in square meters, and thend divide your result by 1500 square meters.  This will give your your answer.  Please note:  your answer will be a COUNT of zebras.  "meters" does not belong in this answer.
