1.a. An investigator is interested in comparing thecardiovascular fitness of elite runners on three different trainingcourses. course one is at, course 2 has graded inclines, and
course three includes steep inclines, Ten runners were involvedfor each course. Heart rates measured on each course are as thefollowing table
Course 1 Course 2 Course 3
132 135 138
143 148 148
135 138 141
128 131 139
141 141 150
150 156 161
131 134 138
150 156 162
142 145 151
139 165 160
Is there a significant difference in the mean heart rates ofrunners on three courses? alpha= 0:05
1.b. The following data is collected on the enzyme activity ofMPI (mannose-6-phosphate isomerase) and MPI genotypes separated formale and female.
a. Is there any significant difference between male andfemale?
b. Is there any significant difference between genotypes?
c. Is there any interaction between sex and genotypes?
