Hypothesis testing:

Very confused with the provided practice example. I tried to find examples for z value. I can't find it

Think of an application where you can use hypothesis testing to test a premises to find z value and p score. Use .05 for your alpha and give the scenario.

How do I use a z test for a BMI example scenario?

Also, I dont understand how to write the

= norm.dist.

And

=norm.s.inv(A)

For the hypothesis testing
