In a previous year, 58% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of
350 females aged 15 and older and finds that 210 are living alone. Is there sufficient evidence at the a = 0.01 level of significance to conclude the proportion has
changed?
Because npo (1- Po) = 85.3
> 10, the sample size is
5% of the population size, and the sample
