Question 1.3. Compute the mean and standard deviation of the eruption durations and waiting times. Then create a table called faithful_standard containing the eruption durations and waiting times in standard units. The columns should be named duration (standard units) and wait (standard units). [9] : duration_mean = np . mean (faithful . column( 'duration') ) duration_std = np. std(faithful . column( ' duration') ) wait_mean = np. mean (faithful . column ( 'wait ' ) ) wait_std = np. std(faithful. column( 'wait' ) ) faithful_standard = Table () . with_columns ( 'duration (standard units)", ((faithful . column ( ' duration') - duration_mean)_ +/ duration_std) , "wait (standard units)", ((faithful. column ( 'wait' ) - wait_mean) / wait_std) ) faithful_standard [9]: duration (standard units) | wait (standard units) 0. 0984989 | 0. 597123 -1. 48146 -1. 24518 -0. 135861 0. 228663 -1. 0575 -0. 655644 0. 917443 1. 03928 -0. 530851 -1. 17149 1. 06403 1. 26035 0. 0984989 1. 03928 -1. 3498 -1. 46626 0. 756814 | 1. 03928 . . .
