Quizplus · Accepted Answer

Based on the given equation (Y = 20 + 30X) and the fact that S_b = 20, we know that the sample mean of Y is 20 and the sample variance of Y is 0. Therefore, F1F1F1S1F1F1F10 = 0, indicating that there is no significant difference between the sample mean and population mean. However, we cannot determine the value of t based on this information alone. We need to know the sample size, standard deviation of Y, and the population mean to calculate the t-value. Therefore, option 1 and option 2 cannot be the correct answer. Option 3 is incorrect because, as mentioned above, F1F1F1S1F1F1F10 = 0, indicating no significant difference between the sample mean and population mean. Option 4 is partially correct because it indicates that F1F1F1S1F1F1F10 = 0, as already discussed. However, the second part of option 4 (F1F1F1S1F1F1F10) cannot be determined based on the given information. Therefore, option E, which includes both 2 and 4, is the best choice as it accurately reflects the information provided.
