3.2.19 statistics students conducted a test to see if people could taste the difference between coke and pepsi. they fill two cups with coke and a third with pepsi. they then asked their subjects which tasted different than the other two. of the 64 people they tested, 22 were able to correctly identify which of the three cups of colas tasted different. determine a 95% theory-based confidence interval for the population proportion that can correctly identify the cola that is different? what is the margin of error from your interval from part (a)?

The confidence interval for population mean is given by :-

, where is sample proportion and E is the margin of error .

Given : Significance level :

Sample size : n= 64

Critical value :

Sample proportion:

Hence, the margin of error = 0.1164

Now, the 95% theory-based confidence interval for the population proportion will be :

Hence, the  99% confidence interval is

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
