A restaurant manager says that 75% of customers are seated within 15 minutes of arriving. A regular customer who never waits more than 15 minutes believes that more than 75% of customers are seated within 15 minutes. A random sample of 125 customers were selected and 105 of them reported that they were seated within 15 minutes of arriving. Is there statistically significant evidence to conclude that more than 75% of customers are seated within 15 minutes? Calculate the standardized test statistic and P-value. Here is a z-table. Enter the standardized test statistic to 2 decimal places and the P-value to 4 decimal places. Standardized test statistic: z = P-value =
