Answer:
Step-by-step explanation:
A. Solve for the mean
Iligan City
42.50+42+42.75+41+42+41.75+41.50
=293.5 ÷ 7 = 41.93 rounded off
Ozamis City
40+39+38.5+41.25+43.5+42+40.75
=285 ÷7 = 40.71
Ang process kase sa pagkuha ng mean ay add mo muna lahat tapos i divide mo sya kung ilang numbers and inadd mo.
