Temperatures in a certain part of the world are normally distributed with Mean 24 and standard deviation 6 when checked at noon each day. (you can Use a Normal Probability Distribution Graph).

a) What temperature Corresponds to one standard deviation above the mean?

b) What is the probability that the temperature is above the answer That you gave in part (a) ?

c) What is the probability, that the temperature is between 21 and 32?

d) How many days of the year have their temperature between 21 and 32 When checked at noon?

e) Using the same mean (24) and standard deviation (6)

What temperature Corresponds to the coldest 20% of all days? (Find the temperature that cuts off the bottom 20% of the distribution)
