Consider the following hypotheses:Ho: p a 90HA: {1' I! 99 The population is normally distributed. A sample produces the following observations: 71 80 68 77 89 81 Conduct the test at the 10% level of significance. [You may find it useful to reference the appropriate table: 2 table or t table} a. Calculate the value of the test statistic. {Negative value should be indicated by a minus sign. Round Intermediate calculations toat least 4 decimal places and final answer to 2 decimal places.) mac—
