I need some help solving this problem, thanks

Ishikawa et al. (Journal of Bioscience and Bioengineering, 2012) studied the adhesion of various biofilms to solid surfaces for possible use in environmental technologies. Adhesion assay is conducted by measuring absorbance at A590. Suppose that for bacterial strain Acinetobacter, five measurements gave readings of 2.69, 5.76, 2.67, 1.62 and 4.12 dyne-cm2.X Your answer is incorrect. (b) Find a 95% confidence interval for the mean adhesion. Round your answers to two decimal places (e.g. 98.76). i 2.11 SUS i 4.63
