For the 3rd Question, part 2. The statement clearly says ALSO which corresponds to : the same 26% who believe it will expand customer base some of them also believe it will help preserve market share. So if there are 100 Latinos. 26 believe it will help expand market share, there could be totally different set of 6 that believe it preservers market share. There is no way to confirm overlap and the "also" in this question.

This was tricky for me to understand as well, but I think I got it. We are looking to find if the total overlap does not go over 25%. If we assume they all overlap that is the maximum percentage we can get. MAXIMUM OVERLAP: Latino = 6%/26% = 23.08% African American = 6%/29% = 20.69% Asian American = 4%/25% = 16.00% Native American = In the case of Native American, the total percentages add up to 99%, so there we know for certain that they do not overlap, thus 0%. Since all the respondent categories' maximum overlap is below 25% we do not need to go further and weight the number of respondents in each category. We know that the overlap is somewhere below 25%.

Hi there! Just FYI, the short url given for Q4 in this video doesn't redirect to the GMAT Club. For anyone else who may be seeing this in 2024 or beyond, use the link in the description instead.

Thanks Rachel for spotting the URL issue.

In the 3rd Q/2, if there's no overlap between respondents who believe that the website could help them expand the customer base and who believe that it would help in preserving market share - would supported still be the answer?

@sudipm7 10 ай бұрын

Same query for Q4/1, what if the 47% some what supporting reducing class sizes and 22% some what supporting adding music classes are completely disjoint?

@marcnasr5674 10 ай бұрын

Regardless of the overlap, only 22% stated they somewhat agreed to add music classes. However, 47/2=23.5 which is more than 22, so it is not possible to have more than half agree to add music classes.

@@mafernandaroca Hope I'm not too late but I've been struggling with the same issue for a while. You have 100 people, 47 of which somewhat agreed for class sizes and 22 somewhat agree to add music classrooms. In order to determine if it's less than 50%, you would need the overlapping section. However, in the worst case scenario (where the % is the highest), even if all 22 where part of the 47, you would still get a % of less than 50% (22/47, 46.8% to be exact). Any other possible overlapping (including the extreme scenario where no one of the 22 are part of the 47, for which the % is 0) has a % of less than 50%. So it can be determined that it is less than 50%, but you cannot know exactly what's the % since you do not know the overlapping section. The question is only asking you if you can determine if it's less than 50% so the anser is "can be determined"

In 3rd Q/2, I think as 25% of 26% = 26/4 = 6.5%. This means that 6% will always be less than 6.5%. Although we can't be sure of the overlap (it can be either all of the 6% being overlapped with the 6.5% or it can be none of it being overlapped) however, we can be sure that these respondents (varying from 0% to 6%) will always be less than the other(6.5%)

@rohitsnful3 3 ай бұрын

If the Q4 could have "True and False" rather than "Can be determined or can't be determined", then will the answer for Q4/1 be the same?

i have a query about making a strategy please assist. If i am 100% sure about right answer to a hard question and i deliberately mark the wrong option and bookmark it for later selecting right answer will it be a good strategy? (as i will probably get an easier next question and later i am anyway marking right option for the bookmarked also.)
