Answer:

B

Step-by-step explanation:

In a number line, closed circle is for less than equal to or more than equal to or equal to. Since your number is n>-2 we will have an open circle.

Second thing is our number n is more than -2. This means it is going to include all the numbers greater than -2 which are -1, 0, 1,2,3...and so on. So to draw this you make an open circle on -2 and draw it towards the side where numbers bigger than -2 are so on the right side.

Suppose that there are 20 numbers in a data set and that they are all different. How many of the values in this data set are bet
antoniya [11.8K]

Answer:

10 Values

Step-by-step explanation:

We would use a set of data for illustration

Given the set of numbers:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20

Since we have an even number of data, the median is in between 10 and 11.

(1,2,3,4,5,6,7,8,9,10),(11,12,13,14,15,16,17,18,19,20)

Lower Half: (1,2,3,4,5,6,7,8,9,10)

  • The median of the lower half is in between 5 and 6. So Q_1 is in between 5 and 6.

Upper Half:(11,12,13,14,15,16,17,18,19,20)

  • The median of the upper half is in between 15 and 16. So Q_3 is in between 15 and 16.

Therefore, we have the [position of the first and third quartiles as:

1,2,3,4,5,Q_1,6,7,8,9,10,11,12,13,14,15,Q_3,16,17,18,19,20

There are 10 values in between the first and third quartiles.
