WebOr maybe we should write this way. If I pick a random T-value, if I take a random T-statistic-- let me write it this way-- there's a 95% chance that a random T-statistic is going to be less than 2.262, and greater than negative 2.262. 95% percent chance. Now when we took this sample, we could also derive a random T-statistic from this. WebWell we can see that our p-value, 0.13, is greater than our alpha value, 0.05. And so because of that, we fail to reject our null hypothesis. And to answer their question, no there is not sufficient evidence to conclude that there is a difference. There's not sufficient evidence to reject the null hypothesis and suggest the alternative.

In statistics, t-scores are primarily used to find two things: The upper and lower bounds of a confidence interval when the data are approximately … WebThis gives you an inverse cumulative probability, which equals the critical value, of 1.83311. If the absolute value of the t-statistic value is greater than this critical value, then you can reject the null hypothesis, H 0, at the 0.10 level of significance.

Webp-value: The area to the right of the t-statistic (2.40) for the t-distribution with 29 degrees of freedom is less than 0.025 but greater than 0.01 (since the 97.5th percentile of this t-distribution is 2.045 and the 99th percentile is 2.462); thus the upper-tail area is between 0.01 and 0.025 and the two-tail p-value is twice as big as this ... WebAnd for this situation where our alternative hypothesis is that our true population regression slope is greater than zero, our P-value can be viewed as the probability of getting a T-statistic greater than or equal to this. So getting a T-statistic greater than or equal to 2.999.
