A random sample of 100 students is taken from a larger population of students in a multi-lecture course and the sample mean (average) of their final grades is found to be 57.5. Suppose it is known that the population standard deviation is 5. Use R Commander to help you test, with a significance level of 0.01, whether there is significant evidence that the average grade for the population exceeds 56. Choose the most correct statement. You test Ho: [ > = 56 versus Ha: p 56 and you obtain a pvalue of 0.001 (TO 3 DECIMALS) and the result is significant. You test Ho: u 56 and you obtain a p-value of 0.001 (TO 3 DECIMALS) and the result is not significant. You test Ho: u 56 and you obtain a p-value of 0.001 (TO 3 DECIMALS) and the result is not significant. The Excel file STATISTICSSTUDENTSSURVEYFORR contains the column BEFPULSEMIN (a numerical variable that measures student pulses before completing an online survey). For education purposes, consider this dataset to be a sample of size 60 taken from a much larger population for statistics students. You test, with a significance level of 0.002, whether there is significant evidence that the average beats per minute for the population exceeds 71.75 beats per minute. Choose the most correct statement. You test Ho: u 71.75 and you obtain a p-value of 0.0004356 and the result is not significant You test Ho: u 71.75 and you obtain a pvalue of 0.0004356 and the result is significant You test Ho: u 71.75 and you obtain a p-value of 0.0008713and the result is not significant You test Ho: [ > = 71.75 versus Ha: u
