Question 42 Chi square is zero when: Expected frequency is greater than the observed frequency O Expected frequency is equal to the observed frequency Expected frequency is the square of the observed frequency Expected frequency is less than the observed frequency A Moving to another question will save this response.
-Sharon is interested in testing the differences between student populations at two different universities. If she randomly selects students from both universities, she is examining _____ sample(s). single dependent independent confounded A chi-square test for goodness-of-fit has a sample size of 50. What are the degrees of freedom for this chi square? 25 The degrees of freedom cannot be determined from the information provided. 50 49
The name given to goodness of fit test was derived based on the hypothesis tested and how good the observed frequencies fit a given pattern. To make a goodness of fitness test, the sample size should be large enough so that the expected frequency for each category is at least 5. There are four commonly used goodness of fit tests: The Chi-Square, Kolmogorov-Smirnov, Anderson-Darling, and Shipiro-Wilk. Observed frequencies, denoted by O, are counts made from experimental data - whereby you...
Why will the chi square value be large when the difference between observed and expected is large?
4. In an experiment there were Nexp values measured. The expected values based on similar measurements are known. Both sets are presented in the Table of data. The question that arose was whether the differences between the observed and expected data are due to chance. Use the chi-square test to determine the probability that the differences arose from chance. Data Index Observed Expected 1 8.00 6.40 2 10.00 13.60 3 16.00 13.00 4 7.00 9.00 5 13.00 10.00 6 11.00...
In performing a chi-square test of independence, as the differences between respective observed and expected frequencies _________, the probability of concluding that the row variable is independent of the column variable increases. A. stay the same B. decrease C. increase D. double
Given the following observed phenotypic ratios, calculate the expected phenotypic ratios and chi square values. Then evaluate the chi square value using a chi square table to accept or reject the null hypothesis at a P value of 0.05. Place the appropriate boxes in correct position in the table

Please help me answer #3. The chi^2 value means nothing on its own-it is used to find the probability that, assuming the hypothesis is true, the observed data set could have resulted from random fluctuations. A low probability suggests that the observed data are not consistent with the hypothesis, and thus the hypothesis should be rejected. A standard cutoff point used by biologists is a probability of 0.05 (5%). If the probability corresponding to the chi^2 value is 0.05 or...
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...
