The adhesive strength of medical monitoring device has a known standard deviation of 0.55 dyne cm. Tests on the first five prototypes of a new model yielded the following values of adhesive strength: 2.96, 5.67, 2.76, 1.26 and 4.21 dyne-cm'. a. What is the 95% confidence interval for the mean adhesion? b. If the manufacturer wants the confidence interval to be no wider than 0.62 dyne-cm2, how many 1. observations should they take?
