Answer:
#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:
- 50 students in the computer club because they would all like to do online testing
- 35 students in her honors math class because it doesn't cover the votes for the whole school
- her 10 closest friends because they will choose what she likes.
#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.
