A quality control technician is checking the weights of a product. She takes a random sample of 10 units and weighs each unit. The observed weights (in ounces) are shown below. Assume the population has a normal distribution. 100, 98, 110, 104, 106, 92, 108, 100, 96, 110 create a vector x in R: x=c(100, 98, 110, 104, 106, 92, 108, 100, 96, 110) 1. What is the point estimate of the population mean? [Select] Note: the point estimate of the population mean (u) is the sample mean (@). So, just compute the sample mean (), i.e., average of the given data. Use the R function: mean() 2. What is the point estimate of the population standard deviation? [Select] Note: the point estimate of the population standard deviation (o) is the sample standard deviation (s). 3. For a 95% confidence interval, what is the t value with 9 degrees of freedom, to = [Select] use the R function: qt() 4. With 95% confidence, what is the margin of error for the estimation of the population mean? [Select] Margin of error = to. n S 2 5. What is the 95% confidence interval for the population mean?
