Need help with question! this chapter is on non parametric tests/ linear correlation. It involves using the Chi-square test, sign test hypothesis, and run test.

A claim is made that there is no correlation between fuel efficiency and price in passenger cars. A sample of 8 models of passenger cars were ranked according to their fuel efficiency and their price. These ranks are given in the table below. Model Fuel Efficiency Price A 7 4 C A 3 D 8 2 E 8 6 6 G 3 H 2 7 Round your answers to 3 places after the decimal point, if necessary. (a) Find the value of the (Spearman's) rank correlation coefficient test statistic. Test statistic: Is = (b) Find the critical values of (Spearman's) rank correlation coefficient if this test is conducted at the 0.2 significance level. Do not type " _ " in front of your answer (the + is already given in front of the answer box below). Critical values: Is = (c) What is the correct conclusion of this test
