21. An ethologist (a person who studies animals in their natural environment) was studying how accurate their new strain of honeybees are at telling their sisters where pollen should be collected and test if they could out perform other strains of bees. The researchers studied 10 bees and their communication behaviors and used a scale of 0 to 100% correct. Here were the following scores for their bees 95, 98, 90, 88, 94, 85, 98, 90, 88, 84% correct. a. Find the mean, variance, and standard deviation of this group. b. Suppose the =88 for other strains of honey bees, what is the z score? c. What is the probability of getting this mean-draw the curve! d. What is the SEM for this particular group?
