type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar(s).
a survey of the students in lances school found that 58% of the respondents want the school year lengthened, while 42% think it should remain the same. the margin of error of the survey is ±10%.
according to the survey data, at least % of students want the duration of the school year to remain the same, and at least % want the school year to be lengthened.
Step1: Calculate minimum for "remain the same"
To find the minimum percentage of students who want the school year to remain the same, we subtract the margin of error from the given percentage. The given percentage for "remain the same" is 42%, and the margin of error is 10%. So we calculate \( 42 - 10 \).
\( 42 - 10 = 32 \)
Step2: Calculate minimum for "lengthened"
To find the minimum percentage of students who want the school year to be lengthened, we subtract the margin of error from the given percentage. The given percentage for "lengthened" is 58%, and the margin of error is 10%. So we calculate \( 58 - 10 \).
\( 58 - 10 = 48 \)
