Margin of Error - correct answer ✔✔how far in either direction from our point
estimate we would like to go: z(σ/√n)
critical value= - correct answer ✔✔z
confidence interval formula - correct answer ✔✔Point estimate ± margin of error
or
Statistic ± (critical value)(st. dev of STATISTIC)
confidence interval - correct answer ✔✔A range of values constructed from
sample data so that the population parameter is likely to occur within that range
at a specified probability. The specified probability is called the level of confidence
point estimate - correct answer ✔✔A single number, based on sample data, that
represents a plausible value of a population characteristic
critical value - correct answer ✔✔number of standard errors/deviations away
from the mean of the sampling distribution to correspond to the level of
confidence
