统计学模拟题3答案（3 answers to statistical simulation questions） A judge (right, wrong. 10 points, 1 points per question) 1. statistics in application statistics may not be numeric values. () 2., the correlation coefficient equals zero, indicating that there is no correlation between variables. () 3. two factor analysis of variance was used to test whether the two population variances were equal. () The continuous product of the 4. growth rate equals the fixed base growth rate of the corresponding period. () In the 5. linear regression analysis, the sample coefficient R2 is the evaluation of the fitting degree of the regression model. () The 6. weighted average index is a variation of the weighted composite index, which has the same weight. () 7. in the hypothesis test, the given significance level alpha is the probability of rejecting the original hypothesis under the condition that the original hypothesis is true. () 8. in sampling survey, allowable error, also called limit error, is the maximum of sampling error. () 9. if the sample size is determined, it is assumed that the two types of errors in the test cannot be reduced at the same time. () 10. if the mode of a group of data is greater than the median, and the median is greater than the arithmetic mean, skewness coefficient is this set of data is less than 0.
