Most testing is ineffective - Hypothesis

I'm having trouble understanding the data requirements for hypothesis testing

Every scenario the computer runs, someone had to write by hand

The Input hypothesis is Krashen's attempt to explain how thelearner acquires a second language – how second language acquisition takes place. The Input hypothesis is only concerned with 'acquisition', not 'learning'.According to this hypothesis, the learner improves and progresses when he/she receives second language 'input' that is one step beyond his/her current stage of linguistic competence. For example, if a learner is at a stage 'i', then acquisition takes place when he/she is exposed to 'Comprehensible Input' that belongs to level 'i + 1'. We can then define 'Comprehensible Input' as the target language that the learner would not be able to produce but can still understand. It goes beyond the choice of words and involves presentation of context, explanation, rewording of unclear parts, the use of visual cues and meaning negotiation. The meaning successfully conveyed constitutes the learning experience.

The Scientific Method - Science Made Simple

I'll confess that I don't really understand Bayesian statistics, and I apologize for not explaining it well. In particular, I don't understand how people are supposed to come up with a prior distribution for the kinds of experiments that most biologists do. With the exception of systematics, where Bayesian estimation of phylogenies is quite popular and seems to make sense, I haven't seen many research biologists using Bayesian statistics for routine data analysis of simple laboratory experiments. This means that even if the cult-like adherents of Bayesian statistics convinced you that they were right, you would have a difficult time explaining your results to your biologist peers. Statistics is a method of conveying information, and if you're speaking a different language than the people you're talking to, you won't convey much information. So I'll stick with traditional frequentist statistics for this handbook.

When we look around us, we can see that these cognitive tools, and many others, have become a part of our culture. In fact, it would be very hard to imagine life without basic cognitive tools such as stories or metaphors. Each of us can learn to use these cognitive tools to enlarge our powers to think and understand, or we can fail to learn to use them.

This is very helpful for me, I finally understand how to answer such a question I the exam, but I don’t understand where the 0.500 is from
And why to substract it from the z value ?!please clear this up for me as am
Just learning about hypothesis testing, I’d also appreciate if you’d explain to me more about the z tables , are they like standard tables?! For all hypothesis testing ? Am a lil lost so please help!!:(

Say you have a set of observations O and a null hypothesis H 0

After a few more years pass, Sara begins to realize that there are limits to her systematic thinking. She starts to appreciate that theories, and even the language she relies on, are too limited and crude to capture everything that is important about the world. She also recognizes that the way she makes sense of the world depends on her unique historical and cultural perspective. At this point, Sara is in the process of developing the fifth kind of understanding called Ironic understanding.

While she is a teenager, Sara begins to focus more on the connections among things. She begins to see that there are laws and theories that can bring together, and help her make sense of, what she originally thought were disconnected details and experiences. In this stage of her life, Sara is developing the systematic understanding of the world called Philosophic understanding.

Several years later, Sara begins to learn and understand her experience through written language. At this point, she is developing the third kind of understanding called Romantic understanding. During this time, she begins to realize her independence and separateness from a world that appears increasingly complex. She relates readily to extremes of reality, associates with heroes, and seeks to make sense of the world in human terms.
