Question 1192866: Studies have shown that Honolulu has an average daily temperature of mu = 73 degrees F with sigma = 5 degrees What is the probability that if we fly to Honolulu , we'll find the temperature falling :
a. Between a nice 70 degrees F and 80 degrees F:
b. Below 65 degrees F (that's sweater weather!)
c. Above 90 degrees F:

z=(x-mean)/sd so 7 is between -3/5 and 7/5
probability 0.6450
-
below 65 is z <-1.6 with probability 0.0548
-
the last is z>3.4 with probability 0.0003
