Webb14 juli 2024 · Calculating p-value. From the observations of the experiment, — If the p-value is less than or equal to 0.05 (critical value), the null hypothesis is rejected.Hence, the conclusion to be drawn is that there is a difference between means of heights of the population from two countries. — If the p-value is greater than 0.05 (critical value), the … WebbLet E 1, E 2, E 3 be three mutually exclusive events such that P(E 1) = `(2 + 3p)/6`, P(E 2) = `(2 - p)/8` and P(E 3) = `(1 - p)/2`.If the maximum and minimum values of p are p 1 and p 2, then (p 1 + p 2) is equal to `underlinebb(5/3)`.. Explanation: Given. P(E 1) = `(2 + 3p)/6`, P(E 2) = `(2 - p)/8` and P(E 3) = `(1 - p)/2`. According to question, P(E 1) + P(E 2) + P(E 3) ≤ 1

WebbInterpreting the Overall F-test of Significance Compare the p-value for the F-test to your significance level. If the p-value is less than the significance level, your sample data provide sufficient evidence to conclude that your regression model fits the data better than the model with no independent variables. Webb10 maj 2024 · For t-Test we look into the t table to find the p-value, the degree of freedom (df) is n-1, i.e., 49 and we look for a value in row 49 to be equal or greater than t, and obtain the corresponding y value to get p-value to be roughly 45%. Since the p-value is 45% and we have a significance level to be 5%, we cannot reject the Null Hypothesis. Webbc. A value between 0.0 and 1.0 d. A negative value e. Infinite 20.
