grandymaker [24]

Answer:

The decision made by the researcher based on this information is to reject the null hypothesis.

Step-by-step explanation:

Two-tailed hypothesis test:

Critical value: $z_c$

Test statistic: z

If $|z| < |z_c|$ , we do not reject the null hypothesis.

If $|z| > |z_c|$ , we reject the null hypothesis.

In this question:

$z_c = 1.96, z = -2.05, |z| = 2.05$

Since $|z| > |z_c|$ , we reject the null hypothesis.

The decision made by the researcher based on this information is to reject the null hypothesis.

Population = 422,000 (1.12)ⁿ .
