Question 21 2 points Consider Ho: M=0 VS Ha:MO. The value of the test statistic, computed from a random sample of 50 observations, is z=-2.0. Calculate the P-value (give answer to 4 decimal places).Question 20 2 points Ho: 02 = 4 must be tested against Ho: O # 4 on a 59% level of significance based on a sample size of 16 with sample variance equal to 6.1. A confidence interval to test this hypothesis is given by: ( (Only give the value of the lower limit and then the value of the upper limit - no commas, semi-colons, blanks or brackets; give limits rounded to 2 decimal places)Question 10 Suppose that Y ,i=1,2..n follows a new distribution called spectacular with parameter V. It is known that : n v Z In( Y) i=1 n - N(0,9) n Suppose a sample of size 10 is available with 2 In(Y)) = 20. i=1 Calculate the two-sided 99% confidence interval for The lower limit is given by The upper limit is given by
