A city's mean minimum daily temperature in february is 22 degrees upper f. suppose the standard deviation of the minimum temperature in february is 5 degrees upper f and that the distribution of minimum temperatures in february is approximately normal. what percentage of days in february has minimum temperatures below freezing (32 degrees upper f )?

97.72%

Step-by-step explanation:

Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 5 degrees.

Let X be the minimum temperature in February

Then X is N(22,5)

To calculate  percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )

Probability that X <32 degrees

=

Convert this into percent by multiplying by 100

97.72% of days in February has minimum temperatures below freezing (32 degrees Upper F )

y/x=18
