Help Me Please Brainliest 20 points and thanks/5 stars

#2 (3rd answer) ask 3 people at each every table in the cafeteria and (5th answer) every 10th person leaving the school at the end of the day

#3 [selection 1] true; [selection 2] false; [selection 3] true

#4 brown toy blocks "likely"; yellow toy blocks "unlikely"; red toy blocks "unlikely"

#5 mean "decreases", median "no change", range "increases"

#7 The number of Pedro's email has less variance than Annika's

Step-by-step explanation:

#2  Amy shouldn't ask:

#4 There are more brown toy blocks so you will be more likely to pick one up, for the yellow and red blocks you are more unlikely to pick one up because of the small amount they both have

#5 Put the quiz grades for least to greatest

15,17,17,19,20 find the mean, median, and range

mean = 17.6  median = 17  range = 5

Now add the next quiz score (3)

3,15,17,17,19,20 find the mean, median, and range

mean = 15.2  median = 17  range = 17

Now compare the two

mean went down, median stays the same, and range went up.

#7 The number of Pedro's email has less variance than Annika's because Annika's number of emails are more spread than Pedro's.
