Question 2:CorrelationsNo THCPost THCNo THCPearson Correlation1.104Sig. (2-tailed).474N5050Post THCPearson Correlation.1041Sig. (2-tailed).474N5050I want to study the dependency of No THC and Post THC. There is no significant linearrelationship between No THC and Post THC with p-value > 0.05 and low value of correlationcoefficient. Since I am applying paired t test I am keen to know about the linear relationshipbetween No THC and Post THC.Question 3:To examine the influence of cannabinoids on human sweetness perception, a paired-samples t-test was performed, t(-2.230, df=49 p = .015, r=.104), suggesting that post-THCsweetness perception (did) appear enhanced compared to the no-THC condition.
Question 4:Consider the null hypothesis, ho: there is no significant difference in the mean betweenFixed (FW.pick) and decreasing (DW.pick). This is tested against alternative hypothesis, h1: themean for Fixed (FW.pick) is more than that of decreasing (DW.pick).The histogram for FW.pick and DW.pick are given below.The mean forFixed (FW.pick) and decreasing (DW.pick) are observed to lie between 0 –50 and 40 – 60. Hence I expect that there is not much significant difference in the mean betweenFixed (FW.pick) and decreasing (DW.pick).Since data is dependent I apply paired t test. the output is given below.Paired Samples StatisticsMeanNStd.
