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). -

The photoelectric effect can be used to measure the value of Planck's constant. NOTE: The following data are fictional, and will give a result that is quite different from the real value of Planck's constant. Be sure that you do not use the real value of Planck's constant in any calculations here. 1 S -1 Suppose that a photoelectric effect experiment was carried out using light with v = 7.56 × 10¹4 s-¹, and ejected electrons were detected with a kinetic energy of 2.41 × 10-¹1 J. The experiment was then repeated using light with = 9.81 × 10¹4 s and the same metal target, and electrons were ejected with a kinetic energy of 9.09 × 10-¹1 J. Use these data to find a value for Planck's constant (in J • s). Hint. It may help to start by thinking about how you would calculate the metal's binding energy if you already knew Planck's constant.

想問這題的C C選項指的不應該是說 買賣NFT比想像中複雜 但文中所指NFT的買賣那麼複雜，那為什麼不是錯的勒

第 39 至 42 題為題組 As we progress further into the digital age, new terms and technologies seem to pop up everywhere. The latest of these is "NFTs" or non-fungible tokens. If something is fungible, it means that it is able to be replaced by an item of identical value, such as currency. Therefore, a non-fungible token cannot be interchanged; it is unique. NFTs are linked to the blockchain-the digital database that supports online cryptocurrencies like Bitcoin and Ethereum. Let's take a deeper look at NFTs and how people can buy, sell, and trade them. In simple terms, NFTs are one-of-a-kind digital works of art. They can take the form of GIFs, tweets, virtual trading cards, images of physical objects, and more. NFTs tend to attract investors who believe in the future of blockchain technology, and who are willing to spend top dollar to obtain a new form of digital currency. For example, Jack Dorsey's first tweet sold for $2.9 million, a video clip of a LeBron James slam dunk sold for over $200,000, and a decade-old "Nyan Cat" GIF sold for $600,000. Clearly, the NFT market is something to be taken seriously. So, the next question is: how does one participate in it? modi naging dato Basically any digital image can be purchased as an NFT.
