I will give you brainlist if correct. Kathy is using her senior project as a platform for her new social app. She interviews 10 of her peers to find out how many texts they send a day. Use the data below to determine if the statement describes the data.
Write True or False in the provided spaces.

0, 25, 1, 0, 15, 4, 10, 12, 10, 13

a)
The mean number of text sent is 19.
b)
The median is 5.
c)
If Kathy were to interview an 11th person they would have to send 42 texts to increase the mean by 2.
d)
Kathy calculated the mean absolute deviation of the original 10 texts as 6.2.

The median would be 10 since its 10 numbers and when we arrange them from least to greatest, the two 10s would be in the middle. And if we have to numbers, in order to find the median, we would add them together and divide them by 2 to get the median in this case is 10.

The mean of the number of texts can be calculated by adding all the numbers up and dividing them by how many there are, in this case there are 10. So, when we add all the numbers up we should get 90. Then, we divide them by 10 and our mean is 9.

The mean absolute deviation of the original texts would be 6.2

An 11th person sending 42 texts in order to increase the mean by 2 would be incorrect as it would actually raise the mean by 3.

132/11= 12
