The critical value = 5.87. State the appropriate decision (reject/fail to reject) regarding the null hypothesis (alpha = 0.05). Then give a brief explanation of what the results mean in the context of this study, given the information you have been provided. I'm not looking for APA here. If you were to reject or fail to reject the null, simply explain what that means using language that anyone should be able to understand
