To determine whether there is a significant difference in the weights of boys and girls beginning kindergarten, random samples of 50 boys and 50 girls aged 5 years produced the following information. Mean Standard Deviation Sample Size Boys 43.5 lb 6.8 50 Girls 38.7 lb 3.5 50 (a) What is the point estimate of the difference in the average weights for 5-year old boys and girls? (Use ?Boys − ?Girls.) lb What is the 95% margin of error for the point estimate you found? (Round your answer to three decimal places.) lb (b) What is the 98% confidence interval estimate of ?Boys − ?Girls? (Round your answers to two decimal places.) lb to lb

Please check with the instructor for approval before taking your data. You may do this project alone or with another person in the class. Take a sample of 30 from the population in which you are concerned. If possible, make your sample a SRS (simple random sample). Then present the following information for your project: State the topic your project is about and the audience surveyed. State the exact question you asked in your survey. Compute the proportion for your sample. Show your computation. Find a 95% confidence interval for p. What is the margin of error for this confidence interval? What is the meaning of this interval with respect to your data and project? Construct and perform a hypothesis test for p at the…
A survey information given below, Sample mean = 5.5, s=2.517, df-8 and confidence level 95% (coresponding test statistic value is 2.303). Based on this information answer the folowing: Which test is appropriate, z-test or t-test? Type either "z-test" or "t-test" A What was the sample size? A Calculate the margin of error. (Report two decimal point, #.##) A Calculate the confidence interval-write lower and uppler value using comma ",". (Report two A If the df decimal point: #.##, #.##) increases to 30 then what will impact on the margin of error? Write either "increase" A If the df or "decrease" or "no change" increases to 30 then what will impact on the confidence interval? Write either "wide" or "narrow" or "no change"
