WebJun 15, 2024 · Using this estimated regression equation, we can predict the final exam score of a student based on their total hours studied and whether or not they used a tutor. For example, a student who studied for 10 hours and used a tutor is expected to receive an exam score of: Expected exam score = 48.56 + 2.03* (10) + 8.34* (1) = 77.2. WebOct 15, 2024 · A p-value of 0.01 means that there is only 1% chance. So lower p-values are good, but how lower is “lower enough” ?. In most research the threshold to what we consider statistically significant is a p-value of 0.05 or below and it’s called the significance level α. So we can set our significance level to 0.05 (α =0.05) and find the P-value. desinfinity https://thehardengang.net
