Question
Show complete solutions, show ALL the steps in the hypothesis testing.
here are the steps for hypothesis:
answer in the form of:
1. state the null and alternative hypothesis (Ho and Ha)
2. decide on level of significance, a
3. collect data and compute the value of the test statistics from the sample data.
4. make the decision. reject Ho if the value of the test statistics belongs in the critical region. otherwise, reject Ho | compute for the p value and make decisions. reject Ho if the p value is greater than or equal to a. otherwise, do not reject Ho.
5. interpret the results.
![The deflection temperature under load for two different types of plastic pipe is

What is the value of critical level from the answer? Explain like this format:
For example, with critical region Z > za since Ha is of the form of u > uo. The critical value is za = z0.05 = 1.645.
