The five basic steps would be of the hypothesis test.
Step 1: Identify the hypothesis, where u is the population mean of the number of light bulbs per household that function as designed
H0: u = certain value vs H1: u not equal a certain value
Step 2: Identify the distribution of the test statistic
Since population standard deviation is unknown, and if the sample size of our study<30, then the distribution would be t n-1 distribution Calculate the sample statistics
Sample mean and sample standard deviation from the dataset
Step 3: Calculate the test statistic
(Sample mean- u)/(Sample SD/√n)
Step 4: Calculate the p-value of the test statistic
Step 5: Compare the p-value of the test statistic to the significance level and then make the decision (Accept/Reject the null hypothesis) and make the conclusion.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
