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. A psychologist believes physical experiences influence perception, such that a hill will appear steeper if…

You wish to determine if there is a linear correlation between the age of a driver and the number of driver deaths. The following table represents the age of a driver and the number of driver deaths per 100,000. Use a significance level of 0.01 and round all values to 4 decimal places. Driver Age 65 69 48 37 49 27 62 64 Ho: p = 0 Ha: p = 0 r= Find the p-value p-value= Number of Driver Deaths per 100,000 22 22 34 Find the Linear Correlation Coefficient The p-value is Greater than a Less than (or equal to) a 23 28 20 The p-value leads to a decision to O Do Not Reject Ho O Accept Ho O Reject Ho 33 33 The conclusion is O There is a significant negative linear correlation between driver age and number of driver deaths. There is a significant linear correlation between driver age and number of driver deaths. O There is insufficient evidence to make a conclusion about the linear correlation between driver age and number of driver deaths. O There is a significant positive linear correlation…
