e F3 3- F4 $ 4 In a survey performed at the University, it was found that 23 out of 239 students interviewed believed that race and racism is an important issue. If we want to construct a 95% confidence interval for the true proportion of students who believe that race and racism is an important issue, what would be the margin of error?

Identify a question you would like to answer using statistics which may be answered using a confidence interval in plain English.   Example:  What is the average GPA of an incoming student at MC   Identify the parameter related to your question and its symbol and its name.   Example:  m, mean   identify the statistic related to your question and its symbol   Example: x(bar), sample mean   List  your data(try to get at least 10 in your sample).   Example:  3.28, 2.41, 3.64, 1.28,3.56, 2.57, 3.10,2.94, 2.45, 3.16, 2.45   Describe your population of inteeest.   Example: All students at MC   Describe your sample.   Example:  11 Studens in my statistics class   Comment on how you obtained your sample   Example: Conducted an email survey of the students in my statistics class   Comment on the bias in your sample   Example;  This sample is biased since it is only people in math 117, who need certain perquisites to take the course, this underrepresents students without the…

The M&M’s in your bag are a sample which will represent the population of all M&M’s. Record how many blue M&M’s are in your bag and the total number of M&M’s. Color Number Blue 15 Total 54   Suppose you wish to find a confidence interval for the proportion of M&M’s that are blue. Would your sample satisfy the assumptions? Explain. 2.Use your sample to obtain a 90% confidence interval for the proportion of M&M’s that are blue. 3. M&M’s website states that 24% of all M&M’s are blue. At the 10% significance level, do your data provide sufficient evidence to conclude that the percentage of blue M&M’s differs from 24%?
