Testing:H0: μ ≤ 26.5H1: μ > 26.5Your sample consists of 38 values, with a sample mean of 27.3. Suppose the population standard deviation is known to be 1.77.a) Calculate the value of the test statistic, rounded to 2 decimal places.z=b) At α=0.03, the rejection region is z < -1.88 or z > 1.88 z > 1.88 z < -1.88 z < -2.17 z > 2.17 z < -2.17 or z > 2.17 c) The decision is to Accept the null hypothesis Accept the alternative hypotheis Reject the null hypothesis Fail to reject the null hypothesis d) Suppose you mistakenly rejected the null hypothesis in this problem, what type of error is that?

The round off errors when measuring the distance that a long jumper has jumped is uniformly distributed between 0 and 4.5 mm. Round values to 4 decimal places when possible. The probability that the jump's round off error is greater than 3.3 is P(x > 3.3) = P(x > 2.1 | x > 0.8) = Find the minimum for the upper quartile
