  1. True or false? When a \(P\)-value is very small, a very large difference exists between the statistic and parameter.
  2. True or false? The alternative hypothesis is one-tailed if the sample statistic is larger than the hypothesised population mean.
  3. What is wrong (if anything) with this null hypothesis: \(H_0=37\)?
  4. True or false: When the sampling distribution is a normal distribution, the standard deviation of this normal distribution is called the standard error.
  5. True or false? Both \(z\)-scores and \(t\)-scores can be test statistics.
  6. True or false? \(P\)-values can never be exactly zero.
  7. True or false? A \(P\)-value is the probability that the null hypothesis is true.
