You need to test the alternative hypothesis that an average is greater than 70. If the population average is 70 and this graph shows the sampling distribution of sample averages, is a sample average of 80 likely to be statistically significant if the significance level is 5%? If so, explain why an average of 80 is likely to reject the null hypothesis. If not, what sample average would be needed to result in a statistically significant result, and why did you choose that value?
