To find the average daily height temperature during summer, we need to calculate the mean of the two sample sets:
Sample 1:
(78 + 82 + 85 + 87 + 90 + 85 + 79 + 86 + 91 + 88) / 10 = 865 / 10 = 86.5
Sample 2:
(81 + 79 + 80 + 86 + 89 + 92 + 82 + 88 + 84 + 87) / 10 = 848 / 10 = 84.8
Now, to find the overall average for both sample sets combined:
(86.5 + 84.8) / 2 = 171.3 / 2 = 85.65
Therefore, the average daily height temperature in Anthony's town during summer is approximately 85.65.
