Answer:

17.39%

Step-by-step explanation:

We can summary the question:

  • Probability of students using Google chrome= 0.49
  • Probability of students using other browsers = 0.51

So the probability that you need to pick 7 students to find 2 students using Google Chrome is:

P(G) = C^{7} _{2} * (0.49^{2})(0.51^{7}) = 21*0.2401*0.03 = 0.1739 = 17.39%

The following table shows the number of classes that
Tresset [83]

Answer:

There are 6 classes we find the median by finding the middle number of the 3rd highest class and 4th highest class, even if this is a decimal.

6/3 = 3+ 0.5

The process would be different if some values are the same values already on the chart total of each class.

ie) 20  31  14  22 20 31

small data like this below you can rearrange

14  20  20  22  31 31  

and see that 21 is the correct value

as there are even numbers, so we choose 20 , 22

and select the middle value = 21

Step-by-step explanation:

If there is an even number of numbers locate the two middle numbers so that there is an equal number of values to the left and to the right of these two numbers. Step 3: If there is an odd number of numbers, this middle number is the median. If there is an even number of numbers add the two middles and divide by 2.
