Explanation & Answer
-x+2y=10
-3x+6y=11
sing equation i) solve for x
-x=10-2y
therefore x=2y-10
substitute value for x n equation 2 to get
-3(2y-10)+6y=11
-6y+30+6y=11
the equation has no solutions since 0y cannot be solved for the equation
correct answer is
d) no solutions

Find the mean and standard deviation of the sampling distribution, Statistics Assignment Homework Help
1.
A farmer divided a field into 1-foot by
1-foot sections and tested soil samples from 32 randomly selected sections in
the field. He finds that the mean pH level of the samples is 5.7 with a
standard deviation of 0.26.
(a) Find
the mean and standard deviation of the sampling distribution of all possible
soil samples of size . Round to three decimal places.
(b) Construct
a 95% confidence interval for the mean pH level of soil samples from every
1-foot by 1-foot section. Show your work. Even if you use technology, show the
expression that is used to determine the margin of error for the interval.
Interpret the interval in a complete sentence.
(c) The
farmer tested soil samples from 34 randomly selected sections from another
field. He found the mean pH level of those samples to be 6.1 with a standard
deviation of 0.34. Construct a 95% confidence interval for the difference
between the mean pH levels of all possible soil samples from both fields. Show
your work. Even if you use technology, show the expression that is used to
determine the margin of error for the interval. Interpret the interval in a
complete sentence.
