A researcher wishes to estimate, with 95% confidence, the proportion of adults who have high-speed internet access. Herestimate must be accurate within 1% of the true proportion.
A) find the minimum sample size needed, using a prior studythat found that 58% of the respondents said they have high speedinternet access.
B) No preliminary estimate is available. Find the minimumsample size needed.
1) what is the minimum sample size needed using a prior studythat found that 48% of the respondents said they have high-speedinternet access?
n = ? (round to nearest whole number as needed)
2) what is the minumum sample size needed assuming that nopreliminary estimate is available?
n = ? (round to nearest whole number as needed)
