2) We have to test, H0: $\mu$ = 26 against H1: $\mu$ > 26.

3) We have to test, H0: p = 0.003 against H1: p < 0.003.

4) We have to test, H0: $\mu$ = 62,900 against H1: $\mu$ > 62,900.

5) We have to test, H0: p = 4.1% against H1: p > 4.1%.

6) We have to test, H0: $\mu$ = 43°F against H1: $\mu$$\neq$ 43°F.
