Math 333 Plz help ASAP
The yield of a chemical process is being studied. From previous experience, yield is known to be normally distributed and σ = 3. The past five days of plant operation have resulted in the following yields 91.6, 88.75, 90.8, 89.83, and 91.4. Find a 95% two-sided confidence interval on the true mean yield. (a) Calculate the sample mean. Round your answer to 2 decimal places. x ¯ = Enter your answer in accordance to the item a) of the question statement (b) Calculate the 95% two-sided confidence interval on the true mean yield. Round your answers to 1 decimal place. Enter your answer; confidence interval, lower bound ≤ μ ≤ Enter your answer; confidence interval, upper bound

Math 333 ASAP plz The comprehensive strength of concrete is normally distributed with μ = 2500 psi and σ = 50 psi. Find the probability that a random sample of n = 5 specimens will have a sample mean diameter that falls in the interval from 2499 psi to 2510 psi. Express the final answer to three decimal places (e.g. 0.987).

An article reported that for a sample of 56 kitchens with gas cooking appliances monitored during a one-week period, the sample mean CO2 level (ppm) was 654.16, and the sample standard deviation was 163.36. (a) Calculate and interpret a 95% (two-sided) confidence interval for true average CO2 level in the population of all homes from which the sample was selected. (Round your answers to two decimal places.) ppm Interpret the resulting interval. We are...

Two catalysts may be used in a batch chemical process. Twelve batches were prepared using catalyst 1, resulting in an average yield of 85 and a sample standard deviation of 3. Fifteen batches were prepared using catalyst 2, and they resulted in an average yield of 89 with a standard deviation of 2. Assume that yield measurements are approximately normally distributed with the same standard deviation (a) Is there evidence to support the claim that catalyst 2 produces higher mean...
