HYPOTHESIS TEST # 1 The Weather Channel runs a program originating in Yellowknife, Canada_ The show is about trucks that get snowbound and the subsequent towing of trucks out of the snow. Yellowknife averages 1577 mm of snow each Winter with stdev = 265 mm. Lars is the only statistician in the Northwest Territory and he claims the average is greater than stated so he tests a sample of 103 previous winters and obtains a sample mean of 1655 mm with stdey = 265 mm. At alpha = 0.01, PROVIDE A DETAILED TEST by inswering the questions below ..... DO NOT USE THE P-VALUE METHOD-USE THE TRADITIONAL METHOD-do not use a t test.

Amit is a statistician for the trail and he claims the time has changed ( most likely due to conditions such as weather and people's desire for more outdoor activity) so he tests a sampling of 121 walker/hikers and finds a sample mean = 2,277 minutes with stdey = 265 minutes. was found to be At alpha = 0.10, PROVIDE A DETAILED TEST by answering the questions below. ---.

Through a nationwide study, the average lease cost for a truck was found to be $ 3,432 per month with stdev, = $ 265. Jamie is a statistics analyst for the trucking industry and claims the average is lower than that stated so he tests 55 active leases and finds a sample mean = $ 3,355 with stdex = $ 265.
