Help me please DIRECTIONS: Write the linear equation for the following situation
A spacecraft leaving the surface of Earth, for example, needs to be going
about 11 kilometers (7 miles) per second, or 25,000 miles per hour, to
enter orbit. Write the linear equation for the Total Distance traveled in
miles for the number of hours a spaceship is at exit speed ((H) X-axis
label)
- Total Distance Traveled Y-axis label
-# of Hours X-axis label
Write your equation below in format (Y label)=(Slope) x (X label) + (Start)

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
