Step 1: find the equation of the least-squares line for predicting manatees killed from thousands of boats registered. because the linear pattern is so strong, we expect predictions from this line to be quite accurate—but only if conditions in florida remain similar to those of the past 31 years. choose the correct answer below:

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).
