The municipality decides that it will increase thetransportation budget if the amount of waiting time for drivers exceed 20 minutes. A sample of 31 main road results in a mean of waiting time of 22.0 minutes andstandard deviation of 5.4 minutes. Use a=0.01.a1) State the altemative hypothesis in this investigation. Insert in the box the letter that corresponds to the correct answer from the answers given below.(a) H1: µ>20(b) Hq: H#20(c) Hq: p<202) The test statistic equalsand the critical value is equal to(Round the test statistic to 2 decimal places).3) Insert in the box the letter that corresponds to the right conclusion from conclusions given below.(a) The test statistics is geater than the critical value, therefore we reject Ho and support Hg.(b) The test statistics is less than the critical value, therefore we do not reject Ho and support H1.(c) The test statistics is less than the critical value, therefore we reject Ho and support H1.(4) Construct a 99% confidence interval to estimate the proportion of white employees in the hight-tech firm:Lower Confudence Limit isand Upper Confidence Limit is(Round to 3 decimal places)
