Explanation:
The Homestead strike was a combination of both a company lockout (the company didn't allow workers to work) and a union strike (where the workers did't want to work). It was a power struggle between one of the darkest and sinister monopolists of the 19th century, Carnegie Steel (led by Andrew Carnegie) and the most powerful workers' union in America, the Amalgamated Association of Iron and Steel Workers.
In 1889 the union won, but Carnegie wanted revenge, so in 1892, he demanded harsher conditions after the initial contract was over and when the union said no, a lockout started. It was bloody and messy, with 16 dead. Carnegie's private army of 300 guards faced 10,000 strikers and things turned ugly soon. The Pinkertons (Carnegie's troops) were "defeated" but too many lives were lost.
Since Carnegie's little was defeated, he asked a bigger fish to help him and the governor sent 8,000 soldiers to arrest any union striker that opposed Carnegie. Finally, Carnegie's millions and corrupt politicians won, and the workers were forced to accept lower wages and more working hours. Those who rejected the forced deal were sent to prison.

Answer:
The correct option is D) The design of the study suffers from selection bias.
Explanation:
In research, Selection Bias occurs when the researcher decides who the respondents are or those who are being evaluated or studied.
Every research ought to be designed in such a way that the respondents are selected at random.
In the information provided, the respondents were selected from a group of people who on a balance of probability were already inclined to decline because it was a list of dissatisfied customers. The chances of them declining to respond or responding with a negative were higher than the chances of them indicating that they would buy and this defeats the purpose of the research. The research ought to have also included a sample of respondents who didn't have the product, who had enjoyed the services of the company and were content, those who didn't even know what the product did until they got the survey.
That way holistic information can be obtained from the research about how different sets of people will react and not just those who are already dissatisfied with the company's product(s).
Some of the ways to avoid selection bias in research are:
- To employ the use of random techniques selecting sample sets from populations.
- To check that the traits or characteristics of the larger population are well represented in the samples selected
