Would someone please walk me through how to work through please?

A study ls given in which scientists examined data on mean sea surface temperatures (in degrees Celsius) and mean coral growth (in millimeters per year) over a several-year period at different locations. Here are the data: 29.69 29.87 30.15 30.22 30.47 30.65 30.90 2.54 2.58 2.69 2.50 2.47 2.38 2.2? Sea Surface Temperature Growth (a) Use your calculatorto find the mean and standard deviation of both sea surface temperature x and growth y and the correlation :- between x and y. Use these basic measures to nd the equation of the least-squares line for predicting y from x. (Round your answers to three decimal places.) i); ' + x (In) Enter the data Into your software or calculator, and use the regrewion function to find the least-squares line. The result should agree with your work in part (a) up to roundoff error. (Round your answers to three decimal places.) i?" + x (c) Say in words what the numerical value of the slope tells you. {Round your answer to three decimal places.) Every increase of one degree Celsius means about fewer mean millimeters of coral growth per year. The patient recoveryr tlme from a particular surgical procedure l5 normally distributed with a mean of 5.9 days and a standard deviation of 2.1 days. What is the 80th percentile For recomlnerylr tlmes? (Round your answer to two decimal places.) days
