4)
• z-value should be expressed to three decimal places: e.g.,
z=1.645.
• Before you start each question, you should determine if you
are dealing with the population mean or proportion since what you
do depends on the type of parameter at hand.
• When handling proportion problems, write/use/plug proportions
as decimals (e.g., not 54%, but .54).
• In the beginning, state clearly if you do a 1-tailed or
2-tailed test. State clearly your H0 and H1 using correct Greek...
