Prior to a new drive through system the mean wait time at a certain fast food restaurant was 96 seconds Use the data in the table below to decide whether the evidence suggests the mean wait time is different than 96 seconds with their new system Assume wait times are normally distributed and use an a 0 10 significance level Use the p value approach 104 8 101 5 84 6 91 1 81 8 81 a For this study we should use t test for a population mean b The null and alternative hypotheses would be Ho u 96 96 0 848 91 9 H P c The test statistic V d The p value 0 4182 e The p value is a f Based on this we should Select an answer the null hypothesis g Thus the final conclusion is that 89 6 101 9 please show your answer to 3 decimal places Please show your answer to 4 decimal places 106 2 O The data suggest the population mean is not significantly different at a 0 10 so there is not sufficient evidence to conclude that the mean wait time is different The data suggest the population mean is not different at a 0 10 so there is sufficient evidence to conclude that the mean wait time is different O The data suggest the populaton mean is significantly different at a 0 10 so there is sufficient evidence to conclude that the mean wait time is different Explain how you found the p value in the last problem
