Question

Instead of having a known sigma equal to 10, suppose you simply do not know what the true population standard deviation is. Instead you compute s, the standard deviation of your sample and find that it equals 10. Based on your data you want make predictions about what the true population mean may be. 1) Given your original sample of 100 students: between what range of values can you be 95% confident that the mean (mu) is? (20 pts) 2) Given your original sample of 100 students: between what range of values can you be 80% confident that the mean (mu) 19(20 pts)

    Suppose you are interested in finding out how happy the students are at UNR. You design a survey that probes aspects of an individual’s emotional life, and using this survey are able to compute an accuracy index score ranging from 0 (completely miserable) to 100 (nauseatingly happy). You know that the standard deviation of the population (sigma) equals 8; however you do not know, and want to know, what the mean of the population (mu) is. Rather than give the...

    Activity Four: Confidence Intervals – Sigma unknown Suppose it takes, on average, 10 days to deliver a computer to a customer. This statistic was generated from observing 100 deliveries. The population standard deviation is unknown, but from your observation of 100 deliveries, you calculate the sample standard deviation to be 2 days. The shipping manager would like to construct a 95% and 99% confidence interval (CI) estimate of delivery time. You estimate the mean delivery time to fall between ___...

(1 point) We are 99% confident that the interval frorn 0 328 to 0 486 actually does contain the true value of the population mean μ There is a 99% chance that the true value ofμ will fall between 0 328 and 0 486. 99% of sample means fall between 0328 and 0486. We are confident that 99% of values between 0.328 and 0 486...
