Assume the population standard deviation is 14.4 ounces. Based on this, construct a 90% confidence interval for the true population mean turtle weight.Give your answers as decimals, to two places ±± ounces please show me what function to use on my ti 84 so I can understand how you got the answer. Im struggling with all of these problems and havent been taught how to solve it by handA laboratory in Oregon is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 60 mEq healthy residents has a mean chloride level of 103 If it is known that the chloride levels in healthy individuals residing in mEq find a 95% confidence interval for the true mean chloride level of all healthy Oregon Oregon have a standard deviation of 42 L residents. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)

O'FJust question 3 fill in the blankTo obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil for a 2-year period. The maximum penetration (in mils) for each specimen is then measured, yielding a sample average penetration of x = 53.9 and a sample standard deviation of s = 4.5. The conduits were manufactured with the specification that true average penetration be at most 50 mils. They will be used unless it can be demonstrated conclusively that the specification has not been met. What would you conclude? (Use a = 0.05.) State the appropriate null and alternative hypotheses.
