Answer:
z=3.8196
Step-by-step explanation:
-We notice that this is a normal distribution problem.
-Given the mean is $8500, standard deviation is $1200 , and n=350, the critical z-value using alpha=0.05 is calculated as:

Hence, the test statitic is z=3.8196
y = 0.22(12) + .99 = 3.63
A 12 minute call will cost $3.63
