null and alternative hypothesis should be stated before any statistical test of significance is conducted. In other words, you technically are not supposed to do the data analysis first and then decide on the hypotheses afterwards. E. In general, it is most convenient to always have the null hypothesis contain an equals sign, e.g. H0: µ = 100 HA: µ > 100 F. The true value of the population... • State a null hypothesis and an alternative hypothesis • Identify type I and type II errors and interpret the level of significance • Determine whether to use a one-tailed or two-tailed statistical test and find a p-value • Make and interpret a decision based on the results of a statistical test • Write a claim for a hypothesis test Hypothesis test • A process that uses sample

  • The alternative hypothesis can be either one-sided or two sided. Two-sided Use a two-sided alternative hypothesis (also known as a nondirectional hypothesis) to determine whether the population parameter is either greater than or less than the hypothesized value.
  • This Hypothesis Testing Calculator determines whether an alternative hypothesis is true or not. Based on whether it is true or not determines whether we accept or reject the hypothesis. We accept true hypotheses and reject false hypotheses. The null hypothesis is the hypothesis that is claimed and
  • Since the null and alternative hypotheses do not overlap, the alternative hypotheses is the complement to the null hypothesis, so in this case the alternative hypothesis would be $\mu \ne 102$. Therefore, summarizing, in this case the null and alternative hypotheses would be:
  • Null hypothesis. In a test of hypothesis, a sample of data is used to decide whether to reject or not to reject a given hypothesis about the probability distribution from which the sample was extracted.
