Step-by-step explanation:

Given :  The average low temperature in the park for May follows a normal distribution with a mean of and a standard deviation of .

Let x represents the temperature in the park for May .

Using formula :

For x= 25

Then by using the standard z-table for right tail test,

Hence, the  probability that this bag will be warm enough on a randomly selected May night at the park= 0.80920
