You developed a way to measure anger people.  Test the claim that the mean score of anger for younger people is equal to the mean score for older people. Use a significance level of .06.  The scores are listed below. Scores for younger people: 25, 33, 19, 8, 39, 29, 28, 18, 41, 3, 27, 35, 14, 25, 36, 4, 11 Scores for older people: 38, 35, 21, 5, 19, 22, 35, 33, 54, 3, 55, 9, 15, 22, 47, 4, 21

Find the percent of the total area under the standard normal curve between the following z-scores. z=-0.86 and z=0.86 The percent of the total area between z- -0.86 and z 0.86 is enter your response here %. (Round to the nearest integer.)

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…
