Respond to one of your colleagues’ posts and explain the benefits and consequences of the “relaxed” level of significance.

A significance of 0.05 corresponds to a CI of 95%. A significance of .10 corresponds to a CI of 90%. You know that using 90%CI is not ok. Be conservative. It is safer.
I should also comment on meaningfulness. Please do not confuse significance with meaningfulness. A result might be statistically significant but very weak. A very weak effect is not meaningful. You would not take any action based on a weak effect.
If the difference is not significant, then that might be meaningful. Learning there is no difference that can be very useful information.
Correlation is not causation. Just because a correlation exists between A and B does not mean A causes B. Since you do not know whether A causes B, results are less meaningful than they might first appear.
This case is saying that the CI is 90%. This is inadequate.

When conducting research, it is important to know what is being researched and how it will be used to implement social change. There must be a research hypothesis and a null hypothesis, which is the opposite of the research hypothesis. The confidence level is typically 99%, 95%, or 90% which will tell us the confidence interval will contain the population mean. The higher the confidence level, the lower the margin of error.
The discussion paragraph stated “meaningful contribution to the literature based upon finding statistically significant”. Just because a relationship between two variables is statistically significant does not mean that the relationship is important theoretically or practically (Frankfort-Nachmias et. al, 2020 p. 247).
The paragraph also stated the “traditional levels of significance to reject the null hypotheses were relaxed to the .10 level. Relaxing the levels to .10 increases the margin of error. According to J. Allright, “adjusting the levels is morally wrong” (personal conversation, December 29, 2020).
