People with high levels of stress have more episodes of respiratory illness, and their illnesses last longer. The following are the number of days when 10 low-stress research participants exhibited respiratory illness symptoms. 16 12 10 19 22 21 12 15 10 14 The mean of this population of numbers is μ = 15.1, and the standard deviation is o = 4.13. Suppose you take a sample of four of these 10 low-stress research participants. The following are the number of days the four participants exhibited symptoms. 22 21 12 15 The mean of this sample of numbers is M = , and the standard deviation is s = 4.80.

Suppose you take a sample of eight of these 10 low-stress research participants. The following are the number of days the eight participants exhibited symptoms. 12 10 19 22 21 12 10 The mean of this sample of numbers is M = 14 and the standard deviation is s = 4.93. Calculate the standard error of the mean for the sample of four: OM = The sample of Calculate the standard error of the mean for the sample of eight: OM = is a better estimate of the population.
