I think it is hypothesis testing
Significance Level (Alpha Level): If the level is set a .05, it means the statistician is acknowledging that there is a 5% chance the results of the findings will lead them to an incorrect conclusion.
Percent means "out of 100" → 5% of 11000 = 5/100 × 11000 = 550.
percent means "out of 100" → 5% of £5.60 = 5/100 × £5.60 = £0.28
Before you ever start to work on a problem with a percent in it, stop and think what 'percent' means, and change the percent to a number that you can do arithmetic with. 'Percent' means 'hundredth'. To change a percent to a real number, either divide it by 100, or move the decimal point two places to the left. (Same thing.) 37 percent means 0.37 50 percent means 0.50 84 percent means 0.84 20.2 percent means 0.202 . 3/5 means 0.6 20.2 percent of 3/5 means (0.202 x 0.6) = 0.1212

A significance level of 0.05 is commonly used in hypothesis testing as it provides a balance between Type I and Type II errors. Setting the significance level at 0.05 means that there is a 5% chance of rejecting the null hypothesis when it is actually true. This level is widely accepted in many fields as a standard threshold for determining statistical significance.
I have always been careless about the use of the terms "significance level" and "confidence level", in the sense of whether I say I am using a 5% significance level or a 5% confidence level in a statistical test. I would use either one in conversation to mean that if the test were repeated 100 times, my best estimate would be that the test would wrongly reject the null hypothesis 5 times even if the null hypothesis were true. (On the other hand, a 95% confidence interval would be one which we'd expect to contain the true level with probability .95.) I see, though, that web definitions always would have me say that I reject the null at the 5% significance level or with a 95% confidence level. Dismayed, I tried looking up economics articles to see if my usage was entirely idiosyncratic. I found that I was half wrong. Searching over the American Economic Review for 1980-2003 for "5-percent confidence level" and similar terms, I found: 2 cases of 95-percent significance level 27 cases of 5% significance level 4 cases of 10% confidence level 6 cases of 90% confidence level Thus, the web definition is what economists use about 97% of the time for significance level, and about 60% of the time for confidence level. Moreover, most economists use "significance level" for tests, not "confidence level".
percent means "out of 100", so 5 percent (5%) is 5/100 "of" means multiply. 5% of 360 = 5/100 x 360 = 18
The word percent means "per one hundred." For example, 5% would be 5 divided by 100, or 5/100.
Percent means out of 100 → 5 % of 580p = 5/100 × 580p = 29p
Percent means "out of 100" → 5% of 11000 = 5/100 × 11000 = 550.
Percent means "out of 100" → 5 % of 2425 = 5/100 x 2425 = 121.25
percent means "out of 100" → 5% of £5.60 = 5/100 × £5.60 = £0.28
