Consider the following sample from a normal population

21.01 20.28 19.18 20.83 19.80 19.31 19.37 20.62 20.26 17.65 19.91 18.88 20.30 20.77 18.88 21.29 19.21 20.06 20.59 20.12

Suppose I want to test H₀ = 19.6 against H_a 19.6. Please make the following correct choices:

a)	reject H0 at = 0.07.

b)

not reject H₀ at = 0.10.

c)	reject H0 at = 0.05.

d)

not reject H₀ at = 0.05.

e)

not reject H₀ at = 0.07.

f)

reject H₀ at = 0.10.
