I need help with these 2 questions! Thank you!
When a person takes
pennies to a coin
counting machine, the
average number of
pennies inserted is
3,215 with stdev = 318
pennies.
If a randomly
selected customer is
selected, find the
probability that they
will insert less than
2,563 pennies.
ON 3
Varner's Incorporated is
the PGA's statistician;
they find that an
average of 208.5 golf
tees are used per round
with stdev = 318 tees.
He samples 318 rounds
and finds a sample mean
of 215 tees and stdev =
318 | tees
Find the
probability that a
sample mean is above 215
tees.
