A consumer products company is formulating a new shampoo and is interested in foam height (in millimeters). Foam height is approximately normally distributed and has a standard deviation of 20 millimeters. The company wishes to test Ho: M = 175 millimeters versus H₁ > 175 millimeters, using the results of n samples. Find the boundary of the critical region if the type I error probability is a = 0.01 and n = 4. Round your intermediate values to two decimal places. Round your answer to one decimal places (e.g. 98.76). XZ i Statistical Tables and Charts

![### Problem Context
A consumer products company is formulating a new shampoo and is interested in foam height (in millimeters). Foam height is approximately normally distributed and has a standard deviation of 20 millimeters. The company wishes to test the following hypotheses:
- Null Hypothesis (\(H_0\)): \(\mu = 175\) millimeters
- Alternative Hypothesis (\(H_1\)): \(\mu > 175\) millimeters
### Objective
Using the results of \(n\) samples, find the boundary of the critical region if the type I error probability (\(\alpha\)) is 0.01 and the sample size (\(n\)) is 4.
### Instructions
Round your intermediate values to two decimal places. Round your final answer to one decimal place (e.g., 98.76).
### Input Box
\[
\bar{X} \geq \, \text{[Input Field]}
\]
### Additional Resources
- Access to **Statistical Tables and Charts** is available for computations related to the normal distribution and critical value determination.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbbba0909-7b4f-4e80-8e24-06dfda2d061e%2Ff1e50372-61f4-419a-bbf1-67f7ea3bf86a%2F1mx4vq_processed.jpeg&w=3840&q=75)
