The mean of the temperatures in the chart is 24° with standard deviation of 4°. how many years had temperatures within one standard deviation of the mean?

Step-by-step explanation:

Given: The mean of the temperatures in the chart is 24° and standard deviation is 4°.

To find: How many years had temperatures within one standard deviation of the mean

Solution: Mean temperature μ = 24 , standard deviation σ =4

The lower and upper bound for temperature within one standard deviation of the mean is given as:

Lower bound = μ - σ = 24 - 4=20

Thus, the Lower bound is = 20

Upper bound = μ + σ = 24+ 4=28

Thus, the Upper bound is = 28

Now, The temperature value between (Lower bound, Upper bound) that is (20, 28) is said to be within one standard deviation of the mean.

Hence 27° is the temperature value that is within one standard deviation of mean.

i dont know if you cant find a way its best to actually add all of them start from 105 tho
