Answer:
Mean of temperatures = 82.3 (Approx.)
Step-by-step explanation:
Given:
Number of days = 7 days
Temperatures in 7 days = 81, 78, 83, 89, 80, 87, 78
Find;
Mean of temperatures
Computation:
Mean = Sum of all observation / Number of observation
Mean of temperatures = Sum of all seven days temperature / Number of days
Mean of temperatures = [81 + 78 + 83 + 89 + 80 + 87 + 78] / 7
Mean of temperatures = 576 / 7
Mean of temperatures = 82.2857
Mean of temperatures = 82.3 (Approx.)
