A study is to be conducted to help determine whether a coin is fair. How many degrees of freedom are there for a chi-square goodness-of-fit test?
Homework Answers
In this case we count the number of heads and number of tails in n trials. Those counted numbers are observed frequency of the chi-square table. And the expected counts for each head and tail are n/2.
As we are concerning two observations, the degrees of freedom for the chi-square goodness-of-fit test is (2 - 1) = 1

Assume that a Chi-square test was conducted to test the goodness of fit to a 3:1 ratio and that a Chi-square value of 2.62 was obtained (Table value is equal to 3.84). Should the null hypothesis be accepted? How many degrees of freedom would be associated with this test of significance?

Which of the statements are correct? A condition for using the chi-square goodness-of-fit test is that all expected counts must be at least two. A condition for using the chi-square goodness-of-fit test is the observations are based on a random sample. The chi-square goodness-of-fit test uses n − 5 degrees of freedom. A) I only B) II only C) I and II only D) II and III only E) I, II, and III

QUESTION 5 In a goodness-of-fit test to see if a set of 100 values were randomly drawn from a normal distribution, the quartiles and median (i.e., the 0.25, 0.5, and 0.75 quantiles) for the normal distribution were used to determine intervals for sorting the data. What is the expected number of values that fall into each interval assuming the 100 numbers were drawn from the normal distribution? QUESTION 6 Consider again the goodness-of-fit described in the previous problem. Assuming that...
