The Sugar Producers Association wants to estimate the mean yearly sugar consumption. A sample of 22 people reveals the yearly consumption to be 32 kilograms (kg) with a standard deviation of 10 kg. Assume a normal population. a-1. What is the value of the population mean? Population mean (Click to select) v a-2. What is the best estimate of this value? Estimate value b-1. Explain why we need to use the t distribution. (Click to select) b-2. What assumption do you need to make? (Click to select) c. For a 90% confidence interval, what is the value of f? (Round the final answer to 3 decimal places.) Value of t 1. Develop the 90% confidence interval for the population mean. (Round the final answers to 3 decimal places.) onfidence interval for the population mean is and
