請問大一統計學這兩題有人看得懂嗎🥲

2. To study the attitude of mother and father towards their daughter participating in the outdoor games, a sample of 200 fathers and 250 mothers was investigated. In these two samples, 120 fathers and 50 mothers preferred their daughter to go for outdoor activities. Can it be concluded at a=0.01 level of significance that the proportion of father is significantly higher than that of mother in preferring their daughters for outdoor activities? 3. A firm has a generous but rather complicated policy concerning end-of-year bonuses for its lower-level managerial personnel. The policy's key factor is a subjective judgment of "contribution to corporate goals." A personnel officer took samples of 24 female and 36 male managers to see whether there was any difference in bonuses, expressed as a percentage of yearly salary. The data are listed here: Gender Bonus Percentage Female 9.2, 7.7, 11.9, 6.2, 9.0, 8.4, 6.9, 7.6, 7.4, 8.0, 9.9, 6.7, 8.4, 9.3, 9.1, 8.7, 9.2, 9.1, 8.4, 9.6, 7.7, 9.0, 9.0, 8.4 10.4, 8.9, 11.7, 12.0, 8.7, 9.4, 9.8, 9.0, 9.2, 9.7, 9.1, 8.8, 7.9, 9.9, 10.0, 10.1, 9.0, 11.4, 8.7, 9.6, 9.2, 9.7, 8.9, 9.2, 9.4, 9.7, 8.9, 9.3, 10.4, 11.9, 9.0, 12.0, 9.6, 9.2, 9.9, 9.0 (1) Is there significant evidence that the mean bonus percentage for males is larger than the mean bonus percentage for females? Use a a=0.05. (2) Estimate the difference in the mean bonus percentages for males and females using a 95% confidence interval. Male

想請問一下，這一大段的意思是什麼，雖然知道該怎麼翻譯，也有統計的基礎，但是翻出來的內容實在無法理解。 ISI 代表刺激間距

olds pooled across contrast conditions were significantly higher at the 30 and 60 ms ISIS compared with the pooled no-sound mean (30 ms= 2.31, df = 8, p = 0.049; 60 ms: t = 3.17, df = 8, p = 0.013). At the 0 and 90 ms ISIS, the increase in threshold was not significant (p>0.05). When contrast conditions were analyzed separately, a marginal effect of sound on orientation judgments at the 26% contrast level was revealed in a paired-samples t-test comparing the no-sound condition with the sound conditions collapsed across onset asynchronies (t 2.248, df = 5, p 0.07). At the 36% contrast level, the data consistently showed the same pattern of variation, although no effect of sound was observed (p > 0.05). -
