Do not round.) What is the value of the test statistic? (Round to two decimal places as needed.) Approximate the P-value. (Round to two decimal places as needed.) Approximate the P-value. The P-value is in the range Use the a = 0.01 level of significance to test the advertised claim. Since the P-value is the level of significance, the null hypothesis. There V sufficient evidence to conclude that the mean wait time is less than 12 minutes. In other words, the evidence the resident's skepticism
