A set of average city temperatures in december are normally distributed with a mean of 16.3° C and a standard deviation of 2°C. What proportion of temperatures are between 12.9°C and 14.9°C?

We have been given that a set of average city temperatures in december are normally distributed with a mean of 16.3° C and a standard deviation of 2°C. We are asked to find the proportion of temperatures that are between 12.9°C and 14.9°C.

First of all, we will find the z-score corresponding to 12.9°C and 14.9°C using z-score formula.

Similarly, we will find z-score corresponding to 14.9°C.

Now we need to find probability of z-score between .

Using normal distribution table, we will get:

Therefore, of temperatures are between 12.9°C and 14.9°C.

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
