An airline's data indicate that this past year, the average time it takes to board their flights is 45 minutes. The airline is considering changing their boarding procedures to reduce the boarding time for travelers. The new procedures were implemented and the boarding times for a random sample of 22 customers was taken to determine if there was a statistically significant decrease in boarding times at a= 0.10 with z = - 0.89 and t= - 1.07. Find the p-value using Excel. (give answer to 4 decimal places with no spaces)
