Answer:
probability = 0.9286
Step-by-step explanation:
given data
mean = $8.30
standard deviation = $4.70
waits parties over a weekend of work = 60
solution
when we earn at least $550 in 60 parties
so average per party will be x =
average x = 9.1667
so now we get here z value that is
...............1
put here value and we get
z =
z = 0.184404
so
P(x>9.1667) = P(z>0.184404)
use standard normal table
probability = 1 - 0.0714 = 0.9286
