Question

Can anyone please help me? I will give you a shiny medal!! c:

Answer 1

I'm not sure what I'm doing wrong, I did the frequency over the total number but I'm not sure what I did wrong :(

Answer 2

0.06 was the only I got correct :(

Answer 3

@agent0smith Show me your math skills and help them

Answer 4

So for the mens I did: 41+24+13+14+6 = 98 so that the sum of frequencies and did:

A. 41/98 = relative frequency of 0.41836

Answer 5

B. 24/98 = 0.2448
C. 13/98 = 0.13265
D. 14/98 = 0.14285
E. 6/98 = 0.0612244

Women:

(sum of frequencies): 18+40 + 13+13+18 = 102
A.18/102=0.1764705
B. 40/102 = 0.39215
C. 13/102 = 0.12745
D. 13/102 = 0.12745
E.18/102=0.1764705

Am I just rounding them incorrectly? Or did my math go wrong?

Answer 6

Why does the table show only two d.p. but say to round to three?

Answer 7

I'm not sure :( the program said for me to: (Round to three decimal places as​ needed.) :/ So I kind of don't know if I rounded correctly..

Answer 8

Was my math correct? Or did I round it wrong? Was it supposed to be up to only 3 significant figures?

Answer 9

Your math looks fine. Idk.

Answer 10

I added more values, and got most correct but now I'm confused on significant figures now :/ two sig figs: 0.01?

Answer 11

I correct them, but I don't know why they all aren't up to the same significant figures :c :/

Answer 12

B. 24/98 = 0.2448

is not correctly rounded in the table

Answer 13

Now it's right

Answer 14

oh, okay, thank you :D but do you know what they actually mean by significant figures? or do they want it all to have the same number placement?

Answer 15

Where does it mention sig figs??

Answer 16

my teacher told me to do that, but in the program, it only talks about rounding to the three decimal places.

Answer 17

Sig figs are different to d.p. Usually used for science classes.

Answer 18

Ahh, I see, since this was data processing i didn't have to go into significant figures.. woopsies. Thank you so much! :D :)

Answer 19
