This topic of statistics was incredibly confusing to me, but this one video has helped me understand completely! Thank you so much :)

[coolmonkey]

Thank you so much!!!!
But I need more videos like this please. Cg50 for the win

This is weird. On the Casio FX 9750Giii it has a different input screen. There is no lower and upper bound option. You have X:Numtrial:P:Save Res:Execute. So this problem is not workable on my Casio based on the screen you have here. Casio prides itself on all their graphing calculators having the same keystrokes for the same problem. However, here they fail. I redid this several times to make sure I hadn't made a mistake.

can you store number on cg50 in stats mode?

[melvinfernandes]

could you do a video on how to do one and two tailed tests please on the cg50. Many thanks

[paris]

how do you store answers when doing these questions?

[skullevo]

Hi, thank you for all the brilliant videos. Can you help me with the following question?

A study shows that 0.9% of a population of over 4, 000, 000 carries a virus. Find the smallest sample from the population so that the probability of the sample having no carriers is less than 0.4.

This is an example in the oxford textbook. I am really struggling to apply these steps with this question. Thank you.

Clear and concise!👍
Thank you. Please could you explain the InvB (Inverse Binomial) again?
I’m currently in Yr12 doing A Level Maths Edexcel. My teacher is using the Classwiz but I have the fx-CG50 so I’ve had to come here for help😅

[Twilight_of_Chaos]

just used this while playing fire emblem to figure out how rng blessed i am with character growth rates lol

[mrmagoo-il]

Yay, at last.
I’ve got both the ClassWizz and the cg50 for Alevel maths.
The cg 50 instruction manual is worse than awful.
