Question

Help, please!

**Problem Context:**

According to a reputable magazine, 32% of all cars sold in a certain country are SUVs. Suppose a random sample of 300 recently sold cars shows that 90 are SUVs. Complete parts (a) and (b) below.

**Task:**

a. Write the null and alternative hypotheses to test that fewer than 32% of cars sold are SUVs.

- $ H_0: p $ [Dropdown Menu with Options: $ >, =, <, \neq $]

- $ H_a: p < 0.32 $
(Type integers or decimals. Do not round.)

b. Report the value of the test statistic (z) from the figure.

- $ z = $ [Text Box for Entering a Value]
(Type an integer or a decimal. Round to four decimal places as needed.)

**Graphical Technology Output:**

An image titled "Technology Output" is provided, featuring a bell curve with a highlighted section on the left shaded in blue. The graph includes:
- A horizontal axis labeled to accommodate z-scores.
- A vertical line at the point of interest.
- The shaded region on the left-hand side corresponds to the p-value area.

**Output Details:**
- Test name: 1-PropZTest
- z-value: -0.7426
- p-value: 0.2289

- Options for printing or marking as done are available.

### Problem Description

According to a reputable magazine, 32% of all cars sold in a certain country are SUVs. Suppose a random sample of 300 recently sold cars shows that 90 are SUVs. Complete parts (a) and (b) below.

### Instructions

**a.** Write the null and alternative hypotheses to test that fewer than 32% of cars sold are SUVs.

**Null Hypothesis (H₀):** p [Select]
**Alternative Hypothesis (Hₐ):** p [Select]

*(Type integers or decimals. Do not round.)*

**b.** Report the value of the test statistic (z) from the figure.

**z = [ ]**
*(Type an integer or a decimal. Round to four decimal places as needed.)*

### Graphical Technology Output
