Hi! Help me with this please. Clean and clear solution. Thank you so much!Hypothesis Tests for Two Samples (Use the 5 Steps). Fred and Martina, senior agents at an airline security checkpoint, carry outadvanced screening procedures for hundreds of randomly selected passengers perday. For a random sample of 30 passengers recently processed by Fred, the meanprocessing time was 124.5 seconds, with a standard deviation of 20.4 seconds. For arandom sample of 36 passengers recently processed by Martina, the correspondingmean and standard deviation were 133.0 seconds and 38.7 seconds, respectively.Using the 0.05 level of significance, can we conclude that the population meanprocessing times for Fred and Martina could be the same? Use Unequal-VariancesT-Test.

Step 1: Denote μ1, μ2 as the population mean processing times for Fred and Martina, respectively.

Answered: Fred and Martina, senior agents at an…
