Suppose the average driving distance for last year's Masters Golf
Tournament was 282.5 yards with a standard deviation of 12.2
yards. A random sample of 30 drives was selected from a total of

A key metric in the cell phone industry is average revenue per user
(ARPU) which represents the average dollar amount that a
customer spends per store visit. Recently, AT&T reported their
ARPU was $67.81. Suppose the standard deviation for this
population is $18.45. What is the probability that the ARPU will be
between $62 and $66 from a random sample of 35 customers?
0.3553

correct answer ✅.2496
The sample means for a population that follows the normal
distribution will also be normally distributed, regardless of the size
of the samples. -
correct answer ✅true
Photo Bomb is an online company that sells packaging materials for
photographers. Suppose their average order size is $208.19 with a

An Epson inkjet printer ad advertises that the black ink cartridge
will provide enough ink for an average of 245 pages. Assume that
this claim is accurate and that the standard deviation for this
population is 15 pages. A random sample of 33 customers was
surveyed about the number of pages they were able to print with
their black ink cartridges. What the probability that the sample
mean will be 246 pages or more?
