A veterinarian wants to estimate the mean weight of a cat in their city. They take a random sample of 19cats and found a mean of 10.9 lbs with a sample standard deviation of 1 lbs. Find the 95% confidenceinterval of the mean. Assume that the cat weights are normally distributed. Do not round in between steps.Round answers to at least 4 decimal places.< Select an answer <

Please write in complete thx. Two machines used to fill soft drink containers are being compared. The number of containers filled each minute is counted for 26 minutes for each machine. During the 26 minutes, machine 1 filled an average of 69.2 cans per minute with a sample standard deviation of 2.1 cans per minute, and machine 2 filled an average of 68.5 cans per minute with a sample standard deviation of 3.1 cans per minute. Assume both populations are normally distributed and the population standard deviations are unequal. Can you conclude that machine 1 is faster than machine 2 at the α = 0.05 level? State the relevant hypotheses, compute the test statistic and p- value, and state your conclusion in context. Describe what committing a Type I error would be in this situation. Describe what committing a Type II error would be in this situation.
