Use the confidence level and sample data to find a confidence interval for estimating the population μ. Round your answer to the same number of decimal places as the sample mean.   From packages received by a parcel​ service, 35 are randomly selected. The sample has a mean weight of 23.8 pounds. The population standard deviation is σ=3.8 pounds. What is the​ 95% confidence interval for the true mean​ weight, μ​, of all packages received by the parcel​ service?

Use the confidence level and sample data to find a confidence interval for estimating the population u. Round your answer to the same number of decimal places as the sample mean.
From packages received by a parcel service, 35 are randomly selected. The sample has a mean weight of 23.8 pounds. The population standard deviation is o = 3.8 pounds. What is the 95% confidence
interval for the true mean weight, µ, of all packages received by the parcel service?
O A. 22.7 Ib < µ<24.9 lb
O B. 22.5 lb < u<25.1 lb
O c. 22.2 Ib < u< 25.4 lb
O D. 22.3 lb < µ<25.3 lb
