1. It is assumed that the mean systolic blood pressure is μ = 120 mm Hg. In the Honolulu Heart Study, a sample of n = 100 people had an average systolic blood pressure of 130.1 mm Hg with a standard deviation of 21.21 mm Hg. Is the group significantly different (with respect to systolic blood pressure!) from the regular population?

   • Set up the hypothesis test.
   • Write down all the steps followed for setting up the test.
   • Calculate the test statistic by hand and also code it in Python. It should be 4.76190. We will take a look at how to make decisions based on this calculated value.

2. If you finished the previous question, please go through the code for principal_component_analysis_example provided in the files_for_lab folder .
