(1 point) a) A random sample of 13 cans of peach halves has a mean weight of 16 ounces and standard deviation of 0.4 ounces. Find a 90% confidence interval for a true standard deviation of the weights of all cans of peach halves. Confidence interval: b) What would be the confidence interval for a true standard deviation if the sample size was 45? Confidence interval:(

9. Consider the mean of a random sample of size 75, X. If S2 is the sample variance and the population is normally distributed with mean y, what is the distribution of 10. The mean weight of peanuts in a sample of size 16 from a barrel is 0.09 ounces. The standard deviation of the sample is 0.015 ounces. What is a 90% confidence interval for the mean weight of all peanuts in the barrel? Assume peanut weights in the...

us ProblemProblem List Next Problem (1 point) The weights of cans of Ocean brand tuna are supposed to have a net weight of 6 ounces. The manufacturer tells you that the net weight is actually a Normal random variable with a mean of 5.95 ounces and a standard deviation of 0.22 ounces. Suppose that you draw a random sample of 43 cans. Part i) Using the information about the distribution of the net weight given by the manufacturer, find the...
