- The value of zα/2 when determine the 92%
confidence interval for p.
- The decision rule (aka, the rejection region) for testing the
following pair of hypotheses at the .05 level of significance when
the population standard deviation is unknown and a random sample of
size 28 is taken.
H0: µ = 18
Ha: µ < 18
- The value of tα/2 when determine the 99%
confidence interval for µ when the sample standard deviation of the
population is unknown and a sample size of 35 was taken from a
normally distributed random variable
- P(Y > 57) where Y has a normal distribution with µ = 64 and
σ = 7.
