How would you use a randomized controlled trial to assess the importance of “quality-quantity tradeoffs” in determining how much parents invest in their children? Can you think of a “natural experiment” that allows for similar inference without so many ethical problems?

I don't understand the whole concept of randomized experiments. What does it mean if the cases are not selected randomly but are assigned randomly to groups? How to determine causality? When do we generalize to the whole population?
What are the criteria for an experiment to be a binomial experiment?
Do you think receiving radiation along with chemotherapy is a better treatment option for cancer? Is this question bias or unbiased? Because there is a chance cancer may return after chemotherapy alone, do you think receiving radiation therapy along with chemotherapy is a better treatment option for cancer? Is this question biased or unbiased? and why?
If a researcher does not uncover sufficient evidence for a treatment effect in a hypothesis test, then they would include the statement of “p< .05” when writing their research report. True or False
I need some help explaining how to do this. I guessed on the answer
Give me an example of a research scenario where you would use an independent samples t-test. You can set up a situation where there is an experimental group and a control group, or maybe you want to compare two other groups of people (parents and non-parents, gender, partnered and single, etc). Give us a summary of what you would want to study, who your sample participants would be, why an independent samples t-test would be the best fit, and what statistically significant results would mean. Don't forget to include your research and null hypotheses!
You recently completed an experiment concerning the effects of carbs on happiness. One group of 11 people are assigned a high carb diet, another group of 11 people are assigned a moderate-high carb diet, another group of 11 people are assigned a moderate-low carb diet, and a final group of 11 people are assigned a low carb diet. If I find that I fail to reject the null hypothesis, what might my next step be? Group of answer choices Change my analysis and alpha to make the finding significant and then run post-hoc tests. 1. Run multiple dependent measures t-tests to see if there are any significant differences between particular groups 2. Run multiple independent samples t-tests to see if there are any significant differences between particular groups 3. Change my hypothesis to see if I can find something significant with a different hypothesis for this study 4. Run home and binge-watch Bridgerton because there is nothing else that should be done statistically
You are a senior in the agricultural sciences department of NCSU doing an internship at a local dairy farm. Farmer Bill is an expert dairy farmer but has no background in quantitative decision making. Bill claims that the milk produced by his grass-fed Jersey cattle has higher protein content than the milk made by his grain-fed Jersey cattle. His evidence? He says he can taste the difference. You decide to put Bill's claim to the test. You randomly sample 21 grass-fed Jersey cattle and 18 grain-fed Jersey cattle, independently of one another, and obtain a sample of milk from each cow. Both histograms appear approximately normal. You test Ho : 4 = H2 VS. HA : H1 > 2. where 4 is the true mean protein content of milk produced by grass-fed Jersey cattle and-u, is that for the grain-fed cattle. Your test statistic is 1.98. Based on this information, which of the following is true ? Select one or more: O a. The sample mean protein content for the milk samples from the grass-fed cattle you…
