QuestionA coffee shop that specializes in shade-grown organic coffee wants to learn more about their business costs. Past datareveals that the cost for one pound of organic coffee beans has a mean of $28 with standard deviation $6. The normaldistribution for the population is shown by the dotted black line.The coffee shop plans to take a random sample of 30 such one pound bags of coffee and will calculate the mean cost of thesample to compare to the known cost. Compute the the mean and standard deviation of the sampling distribution ofsample means for a sample of size 30. Round your answers to the nearest tenth.F2Show your answer by moving the two draggable points to build the sampling distribution.Provide your answer below:0.4-0-3--0-2--0-1-#3The population has a normal distributionwith mean 28 and standard deviation 6.==-2200F3$420 25-F427σ= = 4.1%5-30-2F5<61CF6!
