  3. c) Compute the relevant statistic
  4. d) Make a statistical decision (regarding the null hypothesis)
  5. e) Write a conclusion based on the specific research question
**Hypothesis Testing** Harris (2020) tested levels of well-being in subjects with chronic anxiety undergoing brief therapy with mild psychedelics three months before and again three months after the administration of a single session of therapy. The well-being scores for the 16 subjects are listed in the “Before” and “After” columns in the table below: | Subject | Before | After | |---------|--------|-------| | A | 125 | 133 | | B | 96 | 126 | | C | 115 | 115 | | D | 108 | 119 | | E | 93 | 124 | | F | 98 | 109 | | G | 95 | 72 | | H | 120 | 104 | | I | 107 | 113 | | J | 126 | 118 | | K | 102 | 121 | | L | 116 | 115 | | M | 80 | 94 | | N | 105 | 87 | | O | 123 | 121 | | P | 110 | 118 | This table presents data on well-being scores recorded for different subjects before and after undergoing therapy. Each subject has two corresponding scores, indicating their well-being at two different times. Observing the changes in scores can help deduce the impact of the therapeutic session on well-being.
