This problem is using Minitab
2. The heights of Kindergarten children have an average of 39 inches and a standard deviation of 5 inches. A random sample of size n = 52 is taken and the mean is calculated.
Solve the following questions using Minitab (Remember
to show the outputs of Minitab):
c. What is the probability that the value of the mean
is greater than 38?
d. What is the probability that the value of the mean
is less than 37?
e. What average stature has an accumulated probability of 0.92?

Since the sample size is large enough, we can approximate the distribution of sample mean by normal distribution.
Let 
denotes the sample mean for a random sample of size 52.

There is a group of kindergarten children observed who have two
different shirt colors, red and
blue. Red = 1 and Blue =
0. The sample size of 8 can be formed as 1 1 0 0 0 0 1 0.
What are the lower and upper bounds of the 95 percent confidence
interval for this sample if we believe that the sample is drawn
from a binomial distribution?

Please solve the hypothesis testing problems (#1, and 2) using
Minitab as the tool. For each problem, (1) specify the
business and statistical hypotheses, (2) specify what the Type I
and Type II errors are in this business context, and, the
implications of making those errors, (3) include the results from
Minitab, (4) draw appropriate conclusions to your statistical
hypotheses based on the results, and, finally, (5) present the
business conclusions in a short non-statistical summary.

2. Problem 2 is adapted from the Problem 39 at the end of
Chapter 11. Please solve this problem in Excel and submit your
Excel spreadsheet. The problem is as follows: The state of Virginia
has implemented a Standard of Learning (SOL) test that all public
school students must pass before they can graduate from high
school. A passing grade is 75. Montgomery County High School
administrators want to gauge how well their students might do on
the SOL test,...

2.) For this problem the heights are low enough that the
acceleration due to gravity can be approximated as -g.
(Note: even at low Earth orbit, such as the location of the
International Space Station, the acceleration due to gravity is not
much smaller then g. The apparent weightlessness is due to
the space station and its occupants being in free-fall.)

of the Earth. The net acceleration (provided by...

Children of a certain age in the nation have an average weight
of 85 with a standard deviation of 9.5 lb. A complaint is made that
children are improperly fed in a boarding school. As evidence, a
sample of 14 children of the given age is taken from the boarding
school with an average weight of 89.44 lb. What can be concluded
with an α of 0.05?
