Use the following information to answer the question. An engineer is interested in learning whether there is an association between temperature (°F)and the strength of an automotive plastic cup holder which is measured by finding the pounds per square inch (psi)it takes to break the cup holder. The computer output below shows the results from a regression model in which the breaking point in psi was predicted by the temperature. Assume that the conditions of the linear regression model are satisfied.
-State the decision regarding the null hypothesis and the correct conclusion. State your conclusion using a significance level of 5%.
