Describe the data
Research wants to know what proportion of students graduate of the manicurist class in 2018 from WBI have a California State Board Manicurist License. The researcher asks the following question:
“Are you have a California State Board manicurist License yes or not?”. The Source of Bias is Sampling Bias because the technique used to obtain the individuals to be a sample tends to favor one part of the population over another.

Respond to the following in a minimum of 175 words, please type response:
The standard error of the estimate of the mean is represented by the equation: σ√n Discuss what this equation means, using your own words and explain why we use it. Consider how it relates to the fact that we are making assumptions about the population and not just the sample.

How may I respond to this post from philosophical investigations paragraps 200-315 thx
PI: 220-315
In this particular section of the Investigations we
see Wittgenstein, in line 232, again address one of the main issues
behind what he’s trying to explain about philosophy which is the
loss of understanding between one person or another because the way
we understand and use language is different from other people. In
this particular line, 232, Wittgenstein states that he cannot teach
his way of obeying rules to someone else because someone else may
have a different interpretation of how to obey rules and the
significance of the language behind rules but ultimately both
parties reach the same conclusions. Despite Wittgenstein saying
that everyone’s interpretation of language is different,
particularly in the realm of rules, everyone should reach the same
conclusion because if not everyone is reaching the same conclusion
then therefore there is no validity to language. If there is no
validity to language then it has no practical use for people and
therefore we would not have any understanding of the world and
everything in it.

You have been hired as the new marketing manager for a manufacturer of industrial fork lifts. One of your first tasks is to identify market segments for their products. Thinking about the requirements for effective market segments, what criteria would you use for evaluating the desirability of potential market segments? Identify the criteria, and in a sentence or two explain what each of the criteria means.

Use these 30 different gas prices
2.70, 2.40, 2.58, 2.51, 2.54, 2.57, 2.50, 2.60, 2.65, 2.52, 2.30, 2.55, 2.30, 2.59, 2.54, 2.68, 2.78, 2.75, 2.71, 2.61, 2.70, 2.56, 2.58, 2.60, 2.62, 2.69, 2.55, 2.40, 2.34, 2.56
Part 1 - Estimate the mean price of regular gasoline in the Dayton area by taking a sample. What is the population you will be studying? Think carefully about how you are going to get a good sample to calculate a sample mean and collect the sample. For example, driving around your neighborhood is an example of a convenience sample and should not be done. Think of a more efficient way to collect gas prices that will also cover the whole Dayton area. Write a paragraph or two explaining how you collected your sample and why you think your sample is representative of Dayton gas prices. What is the sample mean? Construct a 95% confidence interval for the population mean price of gasoline in the Dayton area. Explain what this confidence interval tells you.
Part 2 - Compare your sample estimate to the current mean gas in the State of Ohio. Find the mean price of gasoline in the State of Ohio. using http://www.gasbuddy.com/USA. Set up a null and alternative hypothesis to see if your sample for Dayton is enough to prove that the population mean gasoline price in Dayton is different than the mean price in Ohio. Test the hypotheses. Show your work. Using a significance level of 0.05, what is your conclusion?
Part 3 - Compare your sample estimate to the current mean gas in the U.S. What is the mean price of gasoline in the U.S.? using http://www.gasbuddy.com/Charts. Set up a null and alternative hypothesis to see if your sample for Dayton is enough to prove that the population mean price in Dayton is different than the mean price in the U.S. Test the hypotheses. Show your work. Using a significance level of 0.05, what is your conclusion?

Suppose you are studying a population of an animal or plant. You wonder if this population is genetically distinct from neighboring populations (i.e., an ecotype). Briefly state several ways by which you could determine if your population is indeed a locally adapted ecotype. Then describe in some detail how this ecotype could have evolved to be distinct from neighboring populations. Include the concepts of mutation, natural selection, gene flow (migration), genetic drift and inbreeding.
