1 You will perform a significance test of Ho P Po versus Ha

1. You will perform a significance test of Ho: P = Po versus Ha:P>Po.

- What value of z would reject Ho at 5% significance level?

2. You will perform a significance test of Ho: P = Po versus Ha: P < Po.

- What value of z would reject Ho at 5% significance level?

3. You will perform a significance test of Ho: P = Po versus Ha: P is not equal to Po.

- What value of z would reject Ho at 5% significance level?
