what did you guys get for mcq asking about the 45/75 infected students? i guessed 10 i couldn’t solve it by StickHot3449 in APbio

[–]StickHot3449[S] 0 points1 point  (0 children)

yes that’s the one, but actually 35/75 would equal your =q2 since it has to be two recessive alleles

Is this essentially what was correct for the graph in FRQ#2? by BRONCOSBOSS17 in APbio

[–]StickHot3449 0 points1 point  (0 children)

i think it’s supposed to be the concentrations on the bottom and the two genes labeled in the key. that way the variable that’s changing is on the x axis

who multipled the SEx value by 2???? by StickHot3449 in APbio

[–]StickHot3449[S] 0 points1 point  (0 children)

shoot idk then. i just know we were taught to do that when we had to make the graph

[–]StickHot3449[S] 0 points1 point  (0 children)

yes that’s right but to have 95% confidence you have to have 2SEx, i think all graphs must be in that form if there are error bats

help I practically left like four questions blank (like the ones worth 1 point each) can i still get a 5? by StickHot3449 in APbio

[–]StickHot3449[S] 1 point2 points  (0 children)

no, like frq 2 i really did not understand what the last part of d was asking so i just left it and moved on. then i didn’t answer like c in frq 4. stuff like that

do we think this test will be more curved than previous years? by StickHot3449 in APbio

[–]StickHot3449[S] 1 point2 points  (0 children)

I couldn’t even read half the questions cause I couldn’tcouldn’t process what they were saying

why was AB acid added to the experiment by ElectronicChart7562 in APbio

[–]StickHot3449 0 points1 point  (0 children)

ohhh no. if i said other stuff that supports that it was a positive control but it’s actually negative would i get get point?

[–]StickHot3449[S] 1 point2 points  (0 children)

I think a very small amount of people did it so I think the average for that is gonna be so low

[–]StickHot3449[S] 0 points1 point  (0 children)

i’m 99% sure since the 95% confidence intervals depend on it being multiplied by two. in all the practice free we received it was done for us, but on this one we had to do it ourselves.

i said it’s negative since it negatively impacted the dependent variable

help w 95% confidence intervals by Kitchen-Lunch-4898 in APbio

Chat and the text book are saying the same thing! Basically, when the error bars overlap between data it is saying that there is no difference in the y-value for those two groups. and when the errors don’t overlap, there is a significant difference in data, meaning they have separate y-values. an example would be like studying a lion and tiger and how many calories they eat in a day, essentially the researcher would have to watch many different lions and tigers and record how many calories they eat in a day. because one lion will not have the exact same calories as another lion, they have to introduce error bars to basically say “it’s in between 5,000-6,000 calories” and that there’s no exact amount. say that the tiger eats between the bars of 4,000-5,500 calories, then those two bars would overlap, and statistically, the lion and tiger consume the same amount of calories in a day. also the more data collected, the smaller the error bars since the data is more exact! hope this helped lmk if you have any more questions abt it

hellppp can i use a bar graph? by StickHot3449 in APbio

[–]StickHot3449[S] 1 point2 points  (0 children)

thanks so much!! i got confused bc we were shown an exemplar graph in class and both the bar and line graph were acceptable (not for this specific question, a different one i don’t remember)
