Hello Dear teachers, can you please help me o explain the below statistical problem using Minitab procedure??

  • An airline claims that it has an average of 850 daily passengers to its different destinations, with a population standard deviation σ = 62. If in the last 28 days there has been an average of 799 passengers / day, can it be said that daily demand is falling? Use a level of significance α = 0.025
  • When should i use a 1-sample-z or a 1 sample-t function?

Please include minitab pictures and examples, very much appreciate
