Here are some examples of alternative hypotheses: H0: µ > 3.5 H0: p ≠ 0.5 H0: σ < 12 (first example) (second example) Test Statistic - The test statistic is a value that is used to decide whether to reject the null hypothesis. It is a quantity based on the sample data and has a known distribution when the null hypothesis is true.

Any decision is always made about the null hypothesis: Either reject H 0 or fail to reject H 0. The alternative hypothesis (denoted by H 1 or H a or H A) is the statement that the parameter has a value that somehow differs from the null hypothesis. The symbolic form of the alternative hypothesis must use one of these symbols: , <, >. H A:

Let the null hypothesis be that the patient's blood pressure is = 120, and the alternative hypothesis H 1: >120 with signi cance level = 0:05?

An Alternative Decision Rule using the p - value Definition The p-value is defined as the smallest value of α for which the null hypothesis can be rejected. If the p-value is less than or equal to α ,we reject the null hypothesis (p ≤ α) If the p-value is greater than α ,we do not reject the null hypothesis (p > α)

Alternative Hypothesis The Alternative Hypothesis is chosen to match a claim that is being tested, or something you hope is true. Say we are testing for a proportion p. Null Hypothesis is p=p 0. If the Alternative Hypothesis is p>p 0, or if it is p<p 0, these are examples of a one-sided test. If the alternative is p≠p 0, this is called a two-

hypothesis is rejected then we must accept that the alternative hypothesis is true. Note: H 0 will ALWAYS have an equal sign (and possibly a less than or greater than symbol, depending on the alternative hypothesis). The alternative hypothesis has a range of values that are alternatives to the one in The null and alternative hypotheses are ...

Null Hypothesis: The hypothesis to be tested, denoted H o. Assumed to be true. (Null hypothesis contains the equal sign.) Alternative Hypothesis: A hypothesis considered to be an alternate to the null hypothesis, denoted H a. What we believe might actually be true.
