Question 3:
An engineer is designing a kayak that holds a single person
together with a bag. It is known that kayak users have a mean
(person) weight of ?1= 78 and a standard deviation of
?1= 12.3 (all units in kilograms). Denote the (unknown)
population mean and population standard deviation of bag weights,
by ? 2 and ?2 respectively.
The engineer measures bags of 16 randomly selected users. A
sample mean of x = 25.2 and a sample standard...

be posting this if I wanted to see those answers. Thank you!
SHOW WORK!!!!! Full credit will not be given
for answers only. NOTE: for any question asking you to determine a
probability----you MUST write out a probability statement using
proper notation!!!! Probabilities should be DECIMAL form and
rounded to 4 decimal places.
