how to interpret confidence intervals

What if the P-Value is less than 0.05, but the test statistic is also less than the critical value? Since there is only one population, the population mean is actually just a single value that doesn’t change no matter how many times you sample from it. A Computability Proof of Gödel’s First Incompleteness Theorem. Here, we are estimation the average performance of all 1000 students. Why were there only 531 electoral votes in the US Presidential Election 2016? Using of the rocket propellant for engine cooling. It is a confidence in the algorithm and not a statement about a single CI. Shouldn't some stars behave as black hole? This is slightly different from the following incorrect interpretation: There is a 90% chance that the true population mutation frequency of EZH2 lies somewhere between 20% and 30%. Above we looked at the 95% confidence interval, but there is no reason to limit ourselves to 95%. Our model is $Y_i = \beta_0 + \beta_1 X_i + \varepsilon_i$. Asking for help, clarification, or responding to other answers. time, cost). It is either in the confidence interval or not in it. So it makes no sense to assign some population parameter a probability of lying in some range; It either does or doesn’t.

Because the true population mean is unknown, this range describes possible values that the mean could be. So i have interpreted as : "The data provides much evidence to conclude that the true slope of the regression line lies between $.4268$ and $.5914$ at $\alpha=5$% level of significance." Here $95$% confidence interval of regression coefficient, $\beta_1$ is $(.4268,.5914)$. In Monopoly, if your Community Chest card reads "Go back to ...." , do you move forward or backward? Some say that a shift from hypothesis testing to confidence intervals and estimation will lead to fewer statistical misinterpretations. But it is not understandable to those who don't know statistics. Why is the battery turned off for checking the voltage on the A320? But it is not understandable to those who don't know statistics. If I obtain a 95% confidence interval for the test results, what I am actually saying is that 95% of the time, when we calculate a confidence interval in this way, the true test means will be between 75 and 85, and 5% of the time, it will not.
