Statistical Cycle of Inquire (inferential set up). Based on these two samples, Identify all parts of the "inferential set," as discussed in Chapter 7.

Fully demonstrated knowledge of concepts as required.

Answer 1

Answer:

Given,

Confirmed Cases CA: 18517, 3315, 2826, 2018, 1845, 1666, 1401, 1340, 1019

Confirmed Cases WA: 5637, 2243, 1212, 923, 383, 330, 293, 283, 282

For this data,

We use hypothesis test to demonstrate whether or not there is a statistical difference in the number of identified cases:

The hypotheses are:

H0: μ1 - μ2 = 0

Ha: μ1 - μ2 ≠ 0

significance level (alpha) = 0.05

From the output,

Test statistic (t) = 1.2746

Degrees of Freedom = 16

For this, p-value = 0.2207 (using calculator)

As p-value > 0.05 (alpha), we fail to reject H0.

Therefore, there is not enough evidence that there is a statistical difference in the number of identified cases
