This lab combines both the Chi-Squared goodness of fit and test for independence. It also incorporates the use of minitab software.

Chi-squared hyponthesis tests

Name:

Student learning outcomes:

  • The student will select the appropriate Chi-Squared Hypothesis Tests.
  • The student will conduct hypothesis tests and interpret the results.

Candy lab revisited

Suppose the color distribution for the candy from your initial Candy Lab is uniform. Based on the class data, does it appear that the distribution is actually uniform? (α = 0.08)

  1. Ho: Ha:
  2. Which γ 2 - distribution test will be used?
  3. Using Minitab, draw the γ 2 probability graph and label it appropriately. Attach the graph to this lab.
  4. What is the formula for calculating the test statistic?
  5. Calculate the test statistic and the p-value using Minitab. Include the session window output.

test statistic = p-value =

Do you reject or fail to reject the null hypothesis? Why? (Use a complete sentence.)

Write a clear conclusion using a complete sentence.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
