The temperature (in. F) in a city on randomly selected days during the summer are 89,85,90,87,86,91,88 and 89. What is the mean temperature
1. 88.1
2. -8
3. 38 years
4. The mean score for Class 1 is 84.6. The mean score for Class 2 is 83.6. Based on the mean, Class 1 generally performed better on the math test.
5. The median delivery time of Pizza Shop 1 is 21.5 minutes. The median delivery time of Pizza Shop 2 is 20 minutes. Based on the median, Pizza Shop 2 has a faster delivery time.
The mean temperature is:
(89 + 85 + 90 + 87 + 86 + 91 + 88 + 89) / 8 = 87.5°F
Therefore, the mean temperature in the city during the summer is 87.5°F.
To find the mean temperature, you need to add up all the temperatures and then divide the sum by the number of temperatures given.
Adding up the temperatures:
89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 705
Dividing the sum by the number of temperatures (8 in this case):
705 / 8 = 88.125
Therefore, the mean temperature is 88.125 degrees Fahrenheit.
