Question

McNemar test is used to test the hypothesis. Please write a way how critical value has to be taken the quantiles' table: o The order of quantile: o Degrees of freedom: 30. Assume that the aim of research is to compare means of time, which men and women need to buy computer? What statistical test has to be used to test the hypothesis if it is known that time i distributed by normal law and population variances of time in compared groups are equal? O Mann Whitney test; o Student's t test for independent populations; o Student's t test for related populations; o If no correct answer, please write it 31. What decision has to be done if we got that iFls F in testing of hypothesis about equality of variances of two populations? o There is no a statistically significant difference between variances in both populations o The variance of the first population is statistically significantly smaller than the variance of the second population; o The variance of the first population is statistically significantly bigger than the variance of the second population; o If no correct answer, please write it 2. Which of mentioned tests is developed to analyze the differences between expected and observed frequencies of values that variable under interest can gain. o Student's t test for independent populations; o Fisher F-test; o Chi square test for goodness-of-fit (population proportion test); o If no correct answer, please write it

Explanation / Answer

29. Order of quantile is 2*2 tble i.e. it has four cells.

Degrees of Freedom is 1

30. Student's t test for independent populations. Since it has equal variances.

31.There is statistically significant difference between between variances in both populations.

32.Chi square test for goodness of fit.
