[3] Instruction: Draw a conclusion by analyzing the given sets of data using the z test. Use the 7 steps below in answering a word problem in inferential statistics. (Type the answers with solution, NOT HANDWRITTEN + Please put a label with "step #" on every solution).

Note (1): pls refer for the format in the photo below and few example on how to answer each steps.

Note (2): pls refer for the problem on the next photo

Step 1: What are the hypothesis that are presented in the study2
Ho: There is no association between the job classification of employees and their
selected pension plan|
Ha: There is an association between the job classification of the employees.
Step 2: State the alpha level.
a = 0.05
Step 3: Calculate the degrees of freedom.
df = (3 rows - 1)(3 columns - 1),
= 4
Step 4: State the decision rule.
Since X comp168. 09 > x°ci# 9. 49, reject Ho and accept Ha.
Step 5: Calculate the test statistics
X1 - X2
Voiimı + ažlmm
Step 6: State the result.
Step 7: State the conclusion.
Job classification is associated to the pension plan preference of employees.

3. Suppose the Acme Drug Company develops a new drug, designed to
prevent colds. The company states that the drug is equally effective for
men and women. To test this claim, they choose a simple random sample
of 100 women and 200 men from a population of 100,000 volunteers. At the
end of the study, 38% of the women caught a cold; and 51% of the men
caught a cold. Based on these findings, can we reject the company's claim
that the drug is equally effective for men and women? Use a 0.05 level of
significance.

Statistics that allow for inferences or estimates about the population. Inferential statistics enable analysts come to conclusions about the population based on sample data. Inferential statistics cover the basics of inferential statistics, all kinds of hypotheses tests and their confidence intervals, design of experiments, and statistical power and errors. It also includes point estimation techniques, limit theorems, sampling distributions, approximations, and bounds. Correlation, regression, and association are also covered under inferential statistics to infer relationships between variables.
