6. The supply manager at a local ice cream shop claims that 80% of customers prefer chocolate over vanilla. One of the employees believes that is an overstatement. He selects a random sample of 50 customers and found that 30 of them preferred chocolate over vanilla. Which of the following is the appropriate margin of error for a 95 percent confidence interval to estimate the population proportion of all customers that prefer chocolate over vanilla?

Generate a research topic/hypothesis, for example some type of old's wives tale or cliche. identify the population of interest. how will you will randomly select in order to get a representative sample? how you will randomly assign the sample into the experimental and control group? what variable(s) will each group receive? identify the independent and dependent variables. explain how you will control for outside/confounding variables. the following is an example: example: topic: does more time spent studying lead to better grades on exams in college students. population of interest: all students enrolled at college random selection: access database with the names of all students and every 5th student will be involved in study. random assignment: every other student gets sent to the experimental group. experimental group: studies for two hours per night 5 days a week. control group: studies for less than 2 hours per night 5 days a week. independent variable: time spent studying dependent variable: exam scores control for: all students study on same nights, have same instructor, take same posttest, study same material, take exam at same time, etc. everything should be the same between the two groups except the amount of time spent !

Me guys ! software enables between different types of software and between software and hardware. a. communication b. input c. output d. distribution

For each of the processes in model 1, decide as a group if the molecules in the substances have more order (are more organized) before or after the reaction. circle the side of the reaction with more order.
