Can I have some help with this

Consider a right tailed test with a = 0.15 with a one-sided confidence bound at the 85% confidence level. If the observed test statistic was 1.136, what is the conclusion of this test. O We fail to reject the null hypothesis at the 85% confidence level O The null hypothesis is rejected at the 85% confidence level O We cannot find a conclusion based on the information givenGiven a normal random variable X with mean u. = 100 and variance 0'2 = 49, if we randomly observe X=30, is this an unusual observation? " This would be an unusual observation because it lies less than 3 standard deviations away from the mean. "i This would be an unusual observation because it lies more than 3 standard deviations away from the mean. This would not be an unusual observation because it lies less than 3 standard deviations away from the mean. ' This would not be an unusual observation because it lies more than 3 standard deviations away from the mean
