You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately 23%. You would like to be 98% confident that your estimate is within 1% of the true population proportion. How large of a sample size is required?

You will be applying what you have learned in this course by gathering data and running a statistical analysis.    1) To study about the relationship between height and the weight, you need to collect a sample of nine (9) people using a systematic sampling method. a. What is the population of people? b.Where and how are you going to collect your sample? c. Does your sample accurately represent your population? Why or why not? d. Collect the sample and record the data. 2) (CLO 1) Construct a confidence interval to estimate the mean height and the mean weight by completing the following: a. Find the sample mean and the sample standard deviation of the height. b. Find the sample mean and the sample standard deviation of the weight. c. Construct and interpret a confidence interval to estimate the mean height. d. Construct and interpret a confidence interval to estimate the mean weight. 3) (CLO 2) Test a claim that the mean height of people you know is not equal to 64 inches using the…

A programmer plans to develop a new software system. In planning for the operating system that he will​ use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 90​% confident that his estimate is in error by no more than five percentage points question marks? Complete parts​ (a) through​ (c) below. ​a) Assume that nothing is known about the percentage of computers with new operating systems.
