statistics and propability please give me ful answer thanks 1 UIIT is giving two training programmes. Two groups from BSSE were trained for the same task. For the first group trained by programme A, it took a mean of 28.74 hours with a variance of 79.39. For the second group trained by programme B, it took a mean of 20.5 hours with a variance of 54.76. Which training program has less variability in its performance?

Determine which statistic you would use. 1. A psychologist studied if cognitive intelligence was associated with emotional intelligence in50 people. Cognitive intelligence was measured by averaging each person’s scores on tests ofvocabulary and visual problem solving. Emotional intelligence was measured by theparticipant’s score for accurately describing the moment-by-moment emotional reactionsof three people in a filmed interaction 2. A psychologist is interested in whether exercise increases the intensity of REM sleep in adults in three age groups (younger, middle age, older) She obtains 40 people in each age group and randomly assigns half of them to daily exercise or not in a 2 (exercise vs. not) X 3 (age group) design • REM sleep is measured by rating the vividness of dreams recorded in daily dream diaries collected for one week– Bland dreams = 1; very vivid dreams = 5 3.
