A pilot study examining weight-bearing exercise and bone density detect an effect size of 0.8. You are planning the next study and this means option(d) i.e, you will find a clinically significant effect.
A pilot study, also known as a pilot project, test, or experiment, is a small-scale preparatory study carried out to assess the viability, duration, cost, and adverse events as well as to enhance the study design before carrying out a full-scale research project.
One benefit of performing a pilot study is that it may provide early warning about potential failure areas for the main research project, potential protocol violations and if suggested procedures or instruments are appropriate or overly complicated. Pilot studies are scaled-down versions of proposed studies that are used to gauge their viability and identify areas for improvement. They are useful in spotting possible problems early so that they can be fixed without committing to a lengthy and expensive inquiry.
The complete question is:
A pilot study examining weight-bearing exercise and bone density detect an effect size of 0.8. You are planning the next study and know this means: a. If you have a small sample you will overestimate the effect
b. If you enroll a large sample you may be spending more than you need to c. If you have a small sample you will not have enough power to detect this effect size
d. You will find a clinically significant effect

Answer: Well the answer is below
Explanation:
Well when you sleep it gives you energy to which you need in you life and it connects you to your dream whether its good or bad. Dreams are meant for you express how you feel and what you think because dreams are what you make it. Sleeping is so good for you. I love to sleep and it's because you want a healthy jump start to your day whether it's tomorrow, today, or yesterday!! Dreams aren't meant to criticize you or stabilize you but to help you see things in a different perspective whether it's the truth or not.
Sleeping is what we call as hibernating if u didn't know that and we need 8-10 hours of sleep per day. So your question how does sleep and what you dream affect your life, there isn't an answer to it because what you dream affects your sleep. If the dream is good then you will fall asleep faster but is the dream is bad like a nightmare than you won't fall asleep as fast as the good dream. So a dream is what you make it to be
Thanks I really hope this answers your question
