A random sample of 10.000 longleat pine trees are measured for heleht in order to test the hypothesis that the average tree helyt is not equal to 70 feet. Assume the population height is normally distributed with a standard deviation of 8. The sample mean is found to be 70.6 feet. At a 0.05 level of significance which of the following may we conclude about the mean height? The sample mean is higher than the true population mean The population has a larger standard deviation than 8 It is not significantly different from 70 It is significantly different from 70
