Does this imply that Hispanics are underrepresented in the jury system? Test at the alpha=0.05 level of significance. a) What type of hypothesis test should be performed? b) What condition(s) must be first checked in order to perform this hypothesis test? Show appropriate sketches of graphs and/or calculations. c) State the hypothesis. Clearly label the population parameter. d) Perform the test, compute the P-value, and state the decision. Round the P-value to 4 decimal places. e) Relate your conclusion back to the context of the problem using a complete sentence.
