Assume that the life of an engine follows a normal distribution with an average life of 12 years and a standard deviation of 2 years
Assume that the life of an engine follows a normal
distribution with an average life of 12 years and a standard
deviation of 2 years. The seller replaces all engines that fail
during the warranty period without additional charges.
a) If the manufacturer wishes to replace only 1% of the engines it sells, what is the warranty time it must offer?
b) supposes that Puerto Rico sold 30 engines, what is the percentage of probability that more than 1 customer will claim a guarantee?
c) the cost of repairing a $ 1,500 engine. How much money do you expect to spend for the engines you need to repair and are already under warranty?

The variable, Age_Months, follows normal distribution, with a
mean of 56 and a standard deviation of 20. Answer the following
questions.
1) What is the probability that a randomly selected used car is
older than 7 years?
2) What are the minimum and maximum ages (in months) of the
middle 95% of the used cars?
3) Compute the percentage of used cars ranging from 3 years to 7
years.

A quality characteristic X follows a Normal
distribution with mean 100 and standard deviation 2 when the
production process is in control.
Part (a): Suppose that the lower and upper
specification limits are 94 and 106, respectively. What
is the percentage of produced product items that are
non-conforming, i.e., do not conform to the specification limits,
when the process is indeed in control?
Part (b): The management has decided to monitor
the process with and R control charts with a sample...

Power questions. Suppose a population follows a normal
distribution with a standard deviation of 1. We take a random
sample of n= 100 individuals from this population. We know, then,
that sample mean for our population will have the property that
X∼N(μ,1/100).
(a)If μ= 10, find the probability that X >10.1645
(b)If μ= 10.3, find the probability that ̄X >10.1645
(c)Now, consider testing H0:μ= 10 vs H1:μ
>10, using α= 0.05. What is the rejection rule for this test?
