- Find a credible journal article or website where confidence intervals were used to make informed decisions regarding a real world applicationFind the critical t value to use in making an 80% confidence interval for a mean if the sample size is 35. Write your answer with 3 decimal places.a critic points out that this 95 % confidence interval is only accurate if the statistic follows a normal distrubution , or if the normal model is a good approximation. is this true for this data? explain
- We wish to estimate what percent of adult residents in Ventura County like chocolate. Out of 500 adult residents sampled, 367 like chocolate. Based on this, construct a 90% confidence interval for the proportion (p) of adult residents who like chocolate in Ventura County.construct a confidence interval for this data. You should construct a 95% confidence interval for this data. How you do this will depend on whether your data is summarized using a mean or proportions. If you have categorical data, you will have to pick one of the categories and focus on a confidence interval for the proportion for that category, and you only need to do one for that one category. Please show the parts of your equation (point estimate, Z or T, and standard error) in addition to your final result.If the margin of error in an estimate for the mean weight of a shipment is + or -2 pounds at a confidence level of 95 percent, what will be the margin of error at a confidence level of 98 percent? Be sure to show how you arrived at your answer.
- Please don't provide handwritten solution .....If the confidence interval would only contain positive values, what would be your interpretation of this 95% confidence interval regarding this diet program?The ability to find a job after graduation is very important to GSU students as it is to the students at most colleges and universities. Suppose we take a poll (random sample) of 3878 students classified as Juniors and find that 3241 of them believe that they will find a job immediately after graduation. Find the 95% confidence interval for the proportion of GSU Juniors who believe that they will, immediately, be employed after graduation. Use Z = 1.96. Use the unrounded values in Excel to find the answers to #2, #3 and #4. 1. Find the sample proportion of GSU Juniors who believe that they will, immediately, be graduation. 2. The standard error for sample proportion has a value of 3. The margin of error has a value of --
