Given this data, what is the chi-squared value and is it significant? Is the Distribution random?...
After an experiment, a chi-squared analysis of the result was performed. The chi-squared value was determined to be 0 and the degree of freedom was 3. What is the p-value? And is the result of the experiment significant?
suppose x is the mean of a random sample of size n=36 from the chi-squared distribution with 18 degrees of freedom. use the central limit theorem to approximate the probability P(16 < x < 20) ?
PROBLEM 8: It is easy to show with mgf's that the sum of independent chi-squared random variables has a chi- squared distribution with degrees of freedom equal to the sum of the degrees of freedom associated with each of the random variables being summed. For example, if w (df -i) and all W's are independent, then Σ W,-X2 | df n(n+1 2 서 Now, suppose that X, N(i,i), and all X's are independent. Using your result in the previous problem...
Determine the following: (a) The 95th percentile of the chi-squared distribution with v = 11 (Round your answer to three decimal places.) (b) The 5th percentile of the chi-squared distribution with v = 11 (Round your answer to three decimal places.) (c) P(10.283 = x² 35.479), where x? is a chi-squared rv with v = 21 (d) PCX? < 22.465 or x? > 49.802), where x? is a chi-squared rv with v = 35
Consider the observed frequency distribution for the set of random variables. a. Perform a chi-square test using alpha=0.05 to determine if the observed frequencies follow the binomial probability distribution when p=0.50 and n=4. b. Determine the p-value and interpret its meaning. Random Variable, X Frequency, Fo 0 29 1 96 2 151 3 96 4 28 Total 400 The chi-square test statistic is chi squared, χ2=______ p-value=______
For a chi squared χ2-curve with 18 degrees of freedom, find the chi squared χ2-value that has area 0.025 to its right. please show me how to do this on ti 84 calc please!
Chi-Squared In this assignment you will conduct hypothesis testing for Chi-Squared problems for both goodness of fit and independence-you will be given two Chi-Squared problems. For the Chi squared goodness of fit problem you need to: (1) state the populations and hypotheses; (2) solve for a Chi-squared goodness of fit test and show your work; (3) compute the answer using the SPSS program and paste the output information; (4) state the answer using proper APA format; (5) answer the question....
(a) Let X, have a chi-squared distribution with parameter V, and let X, be independent of X, and have a chi-squared distribution with parameter vz.

Discuss the following: (10 points) What type of data can be examined using the Chi-Squared Test? What is the only constraint in using Chi-Squared Tests? What problems can be caused by the way the data have been grouped?
im confused about using the Chi square value to answer these questions Complete the Chi Squared analysis below by filling in the empty white cells. Do not round numbers up until the very end (the final chi squared value) which you can round to one decimal place. It's best to do this in Excel or another spreadsheet program.
