求翻译：r²=0.67意味着总理差平方和的67%杯样本回归直线解释，有33%未被解释。故样本回归直线对样本点的拟合程度还可以。给出显著性水平α=0.05，查询t分布表，得临界值2.262，因为4.29大于2.262，所以拒绝原假设H0，即回归系数显著不为零。即城镇居民年人均可支配收入X对年人均鲜蛋需求量Y有显著影响。是什么意思？

r ² = 0.67 means that the Prime Minister of the squared difference and 67% cup sample regression line explained 33% unexplained. So the sample regression line can also fitting degree of sample points. Given the significant level of α = 0.05, to query t distribution table, a threshold of 2.262, becau

R2 = 0.67 means that Prime Minister square and 67 per cent of its regression line sample cup explained that there were 33 per cent have not been explained. The sample linear regression of the sample points of the degree. To a significant level of effort, the query T = 0.05 distribution list, and a c

r ² =0.67 meant premier misses the sum of squares 67% cup of sample return straight line to explain, some 33% had not been explained.Therefore the sample return straight line to the sample point fitting degree is alright.Gives the significance level α=0.05, inquires the t distribution list, results

R ² = 0.67 meant Prime Minister 67% Cup samples of squares regression line explained that 33% have not yet been explained. Sample level regression of a line of sample points can also be. Given a significance level α = 0.05, queries t distribution table, threshold 2.262 because 4.29 than 2.262, so re
