For a sample of 100 wheat fields, the mean yield was 10 tons/acre and the standard deviation 2. Approximately how many fields out of the 100 should have yields in the 8 to 12 ton range? Show work.
taffyleg said:I'm hoping the answer is 68. I don't understand at what point you differentiate betwen multiplying by 95.4% or 68.3%.
A practice problem is a specific question or scenario that is used to test or develop a person's skills or knowledge in a particular subject or field. It is often used in educational settings to help students apply what they have learned and improve their understanding of a topic.
Practice is important in problem-solving because it helps to improve critical thinking skills and build confidence. By practicing and encountering different types of problems, individuals can learn how to approach and tackle various challenges effectively.
Some effective strategies for solving practice problems include breaking the problem down into smaller steps, using visual aids or diagrams, checking for mistakes, and seeking help or guidance when needed. It is also important to stay organized and focused while solving a problem.
Practice problems are often used in scientific research to help scientists test hypotheses, develop new methods, and improve their understanding of a particular concept or phenomenon. They allow researchers to apply their skills and knowledge in a controlled setting and make new discoveries.
Some resources for finding practice problems in science include textbooks, online learning platforms, scientific journals, and educational websites. These resources may provide sample problems, practice exercises, or interactive simulations to help individuals practice and improve their skills in various scientific fields.
