Which is the formula for the alternative hypothesis?
The formula for the alternative hypothesis is: Ha= p >p0, < p0≠ p0. The formula for the test static is: \(z = \frac{\hat{p}-p_{0}}{\sqrt{\frac{p_{0}(1-p_{0})}{n}}}\) Remember that, p0 is the null hypothesis and p – hat is the sample proportion. Also, read:
How to determine the null hypothesis for linear regression?
To determine if there is a jointly statistically significant relationship between the two predictor variables and the response variable, we need to analyze the overall F value of the model and the corresponding p-value: Overall F-Value: 23.46 P-value: 0.00

AN alternative hypothesis is the other speculation which is reciprocally exclusive to the null hypothesis.
This speculation is a fact that researchers endeavor to disprove.
