Question
Consider the following hypothesis test.
The following results are for two independent samples taken from two populations.

#### Sample Data
- **Sample 1:**
- \( n_1 = 80 \)
- \( \bar{x}_1 = 104 \)
- \( \sigma_1 = 8.4 \)
- **Sample 2:**
- \( n_2 = 70 \)
- \( \bar{x}_2 = 106 \)
- \( \sigma_2 = 7.6 \)
#### Questions
Enter negative values as negative numbers.
a. What is the value of the test statistic? (to 2 decimals)
[Input Field]
b. What is the \( p \)-value? (to 4 decimals)
[Input Field]
c. With \(\alpha = 0.05\), what is your hypothesis testing conclusion?

Transcribed Image Text:### Hypothesis Test Example
Consider the following hypothesis test:
- Null Hypothesis (\(H_0\)): \(\mu_1 - \mu_2 = 0\)
- Alternative Hypothesis (\(H_a\)): \(\mu_1 - \mu_2 \neq 0\)
The following results are for two independent samples taken from two populations.
