In 1882, Albert Michelson collected measurements on the speed of light ("Student t- distribution," 2013). His measurements are given in following table: Table: Speed of Light Measurements (km/sec) 299883 299816 299778 299796 299682 299711 299611 299599 300051 299781 299578 299796 299774 299820 299772 299696 299573 299748 299748 299797 299851 299809 299723 Find the speed of light value that Michelson estimated from his data using a 95% confidence interval by answering the following questions:(i) Determine sample mean x : Enter in decimal form to nearest whole number. Do not enter units of measure. A/ (ii) Determine sample standard deviation s : Enter in decimal form to nearest thousandth. Examples of correctly entered answers: 0.001 0.020 0.500 5.307 1.715 A/ (iii) Determine degrees of freedom df value: Enter value as whole number
