Please show calculation using minitab

  1. During engine tests, you measure the thrust (in pounds)10 times and obtain this data:

4061

3637

3215

4581

4373

4138

3701

3244

4520

4298
  1. Can the normal distribution be used with this data? Use the Central Limit Theorem (CLT) to explain why we can or cannot assume that these values are from a normal distribution. Do you need to make any assumptions in order to apply the CLT?
  2. Calculate the mean and variance for this sample.
  3. (Assume that you can use a normal distribution...) Use a hypothesis test to determine if the mean thrust is greater than 3700. Use alpha = .05. Explain the result.
