The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference.
T+6=24. The value the bakes the equation true is 18. To find this, you would subtract 6 from 24, which would be 18. If you add 6 marbles to 18 marbles, that would be 24, therefor, Tim would have 18 marbles, making Nirja have 24 marbles. I'm 100% this is true. Hope this helps! Please mark brainiest! :)
