Yes.

The correlation between the expected z-scores and the observed data,

nothing,

exceeds

the critical value,

nothing.

Therefore, it is

reasonable

to conclude that the data come from a normal population.

Yes.

The correlation between the expected z-scores and the observed data,

nothing,

exceeds

the critical value,

nothing.

Therefore, it is

not reasonable

to conclude that the data come from a normal population.

No.

The correlation between the expected z-scores and the observed data,

nothing,

does not exceed

the critical value,

nothing.

Therefore, it is

reasonable

to conclude that the data come from a normal population.

No.

The correlation between the expected z-scores and the observed data,

nothing,

does not exceed

the critical value,

nothing.

Therefore, it is

not reasonable

to conclude that the data come from a normal population.
