    The document contains output from two regression analyses. For the first analysis, all independent variables have p-values less than 0.05, indicating they have significant evidence to influence the dependent variable. The F-statistic is also significant, meaning the regression model fits the data better than the average of the dependent variable. For the second analysis, the independent variable has a p-value less than 0.05, meaning it significantly influences the dependent variable. The F-statistic is also significant, indicating the regression model is a good fit for the data.

    Find the missing values and find out whether the independent variables have significant evidence using

    p-value,
    confidence interval and significant F. SOLUTIONS ARE NOT REQUIRED (Hint: find the CRITICAL VALUE for intervals)
