It randomly surveys 200 people. The sample average is 23.7 hours. There is a known population standard deviation of 6.0 hours. The population distribution is assumed to be normal.NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed.

1 - Almost all processes, regardless on whether they are goods or services, exhibit some type of variation in their output. For example, a box of cereal may say that it contains 16 ounces, but in reality, it may be a little bit more, or a little bit less. The machine pouring the cereal into the box may not be adjusted properly, and it may only put 15.8 ounces in each box, on the average. This would be considered an...

1.) Accrotime is a manufacturer of quartz crystal watches.
Accrotime researchers have shown that the watches have an average
life of 30 months before certain electronic components deteriorate,
causing the watch to become unreliable. The standard deviation of
watch lifetimes is 10 months, and the distribution of lifetimes is
normal.
(a) If Accrotime guarantees a full refund on any defective watch
for 2 years after purchase, what percentage of total production
will the company expect to replace?
(b) If Accrotime...
