I Will Give Brainiest Please Answer And Explain Nummber 3

Answers

Answer 1

Answer:

Part A: 56

Part B: 43.9

Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean

Step-by-step explanation:

Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.

Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.

Part C: explanation in answer.

Hope this helps :)

Answer 2

Answer:

for part a you can just go to an excel numbers in a column then click sum then click medien then select the column.

Step-by-step explanation:

So it says read less thann 25 books --> that means the numbers are 13,14,14,16,19,21,21,22,23, and 24 --> a total of 10 numbers

Then it says read more than 35 books --> that means the numbers are 37,41,42,43 --> a total of 4 numbers

Now, it says how many more --> that means you subtract 4 by 10 = 10 - 4 = 6

Therefore the answer is 6 more students read less than 25 books than read more than 35 books.

total of 10 numbers

Then it says read more than 35 books that means the numbers are 37,41,42,43 -- > a total of 4 numbers

Now, it says how many more --> that means you subtract 4 by 10 10 -4 = 6

Therefore the answer is 6 more students read less than 25 books than read more than 35 books.
