A research intern would like to estimate, with 90% confidence, the true proportion of employees who hold two jobs. No preliminary estimate is available. The researcher wants the estimate to be within 3% of the population mean. The research intern has a table to use: z0.10 z0.05 z0.025 z0.01 z0.005
1.282 1.645 1.960 2.326 2.576
They complete the calculation for the minimum sample size as follows:
n = 1.645^2(0.5)(0.5)/3^2
= 0.169
Which the intern then rounds up to 1. Which value in the calculation is incorrect?
