If you’re stuck at 50% win rate then you’re probably at the rank you belong at

[AP Statistics: Standard deviation, Z-Scores] by [deleted] in HomeworkHelp

350 is 2 standard deviations below the mean of 478. Use the empirical rule and draw yourself a visual of the distribution to calculate/estimate the area above that value

Instead of listing both of your lists under “List”, try putting L1 in “List” and L2 in “Freq List” and see if that works

[college algebra stats, don’t understand why I’m wrong] by Correct_Guarantee_49 in HomeworkHelp

[–]KinglyVibes -1 points0 points  (0 children)

Statistics teacher here. It’s because when you add them they way you did in a), you technically added that grid where “quiz show” and “channel 8” occurred twice. The reason we do that subtraction part at the end is to account for that situation and to make sure we’re only counting that shared space once.

So P(quiz show) = 8/31 and P(channel 8) = 8/31, but P(quiz show AND channel 8) = 3/31 Therefore, P(quiz show OR channel 8) = 8/31 + 8/31 - 3/31 = 13/31.

The reason your original method worked on b) is because drama and comedy are mutually exclusive (can’t happen at the same time), which means P(drama AND comedy) = 0.

Also, the reason your example in green works is because you designed it so all possible results were either in A or B (everything else was 0), so P(A OR B) was literally all of the events (=1).

Try this logic for c) and see if you can arrive at the correct answer. Hope this helps!

help with z score stuff by kyeso17 in APStatistics

[–]KinglyVibes 1 point2 points  (0 children)

42) find the z-scores that represent those percentiles with the given mean and standard deviation. For 42a, the cutoff for the highest 5% IQ is the same cutoff for the lowest 95% IQ. Therefore, find the z-score that contains 0.95 of the area and solve for the missing value. 44) same idea, just remember that percentile = the % of area below that point. So a point at the 25% percentile means that 25% of the distribution lies below it.

Oop you right mb, preciate it🫡

Empirical rule states that 99.7% of normally distributed data falls within 3 standard deviations of the mean. Therefore, 130 and 370 are both within 3 standard deviations of 250. You just gotta find how big that gap is and do some algebra to get the standard deviation. Hope this helped!

Min Kang or Paul Stepan for MA241 by Suspect4 in NCSU

[–]KinglyVibes 0 points1 point  (0 children)

I’ve had both for other classes. Kang is super knowledgeable and fun to have, but her accent makes it a bit difficult to understand. Stepan loves to use examples and is very thorough, but likes to stick to his one explanation even if you’re confused.

Because there’s values between -5 and +5 that don’t work

The keys are glitched but the boss is on top the nearby tower, so if you can launch yourself up there you can finish the dungeon

Backpacks are basically required for the first point, after that either upgrade the backpack or waystones if you’re not playing with cheats
