Answer 1

Answer:

Example 0-30 in 0-5 5-10 10-15 etc... upto 25-30

a) 12 and 15 or 10 and 15

b) none

c) none

a) Confidence Level Margin of Error Error Bar

68.3%, sx 12.2857 ±2.275 (±18.52%)

so a0 could be also 12.2857 - 2.275 = 10

Answer therefore may be 10 and 15

So try do a histogram go in 10's across 1-10,10-20,20-30,30-40,40-50

And if mean is 43 then you would need to multiply everything inside box by 0.3 before you can start the y axes  

questions like this start with 0 - 50
