POST MAT220 UNIT 7 AND UNIT 8 DISCUSSIONS

UNIT 7Hypothesis testing has come under scrutiny and a sense of skepticism
over the past few years by experts in all fields where hypothesis
testing is utilized. Based on what you have covered in the course
through Unit 7, discuss the pros and cons of hypothesis testing from
your viewpoint. Why do you think hypothesis testing can lead to
skepticism in general?UNIT 8AQuestion 8 APick
any two variables that you feel may be related and estimate what you
think the strength of the correlation coefficient would be for those two
variables. In your response, estimate the value of r. For example,
specify a strong (.7 to .9), medium (.4 to .6), or low (0 to .3) value
for r. The value of the coefficient can be positive or negative. For
example, consider an increase in police patrols in a neighborhood and
the number of burglaries that occur in that neighborhood. I would say
that would be a strong inverse relationship with an r value of -0.8; as
one (patrols) increases, the other (burglary rate) goes down. Describe
the factors that you think would contribute to why the variables would
have the relationship that you estimate it to be.UNIT 8BQuestion 8 BNow
that you have completed this course in Statistics, please describe a
concept covered in the course that you feel might be of assistance to
you now or in the future. For example, using charts and graphs to
graphically describe data at your job, or using one of the sampling
methods discussed at the beginning of the course to generate sample
data. Please be specific in explaining how you would use what you have
learned in class to your benefit.
