WebThen, if the alternative hypothesis were true, we should expect \(X_i - m_0\) to yield more positive (+) signs than would be expected if the null hypothesis were true: In that case, we should reject the null hypothesis if n −, the observed number of negative signs, is too small, or alternatively, if the P -value as defined by:
WebNov 22, 2024 · Here are some examples of the alternative hypothesis: Example 1. A researcher assumes that a bridge’s bearing capacity is over 10 tons, the researcher will then develop an hypothesis to support this study. The hypothesis will be: For the null hypothesis H0: µ= 10 tons. For the alternate hypothesis Ha: µ>10 tons. WebAs stated above, the null hypothesis is formalized as an equal sign (H0 =), while the alternative hypothesis utilizes either a greater than or less than sign (Ha > / Ha <). Furthermore, the variables in the two hypotheses are represented differently, with the alternative hypothesis containing an additional factor (the cause and effect relationship).
