a quality control specialist for a restaurant chain takes a random sample of size 10 to check the amount of soda served in the 16 oz. serving size. the sample mean is 13.90 with a sample standard deviation of 1.52. assume the underlying population is normally distributed. we wish to construct a 95% confidence interval for the true population mean for the amount of soda served. what is the error bound? (round your answer to two decimal places.)

boundis [12.96, 14.84] when standarddeviationis 1.52 andconfidenceinterval is 95%.## What is confidence interval?

population(sample space) that follows a certain probability distribution is known as aconfidenceinterval. A selected population statistic is built into the interval with a specified probability. An estimate’s level of uncertainty is described by a confidenceinterval, which is a range of numbers. Being confident is having a realistic, comfortable sense of self-assurance in both your talents and judgment. Feeling superior to others is not a prerequisite for confidence. It’s a subdued inner conviction that you can.deviationis 1.52 and the confidenceintervalis 95%, theerrorlimit is [12.96, 14.84].confidenceinterval,
