The value = 0 . 30 is outside the 10% likelihood interval. Answer: False To obtain the 10% likelihood interval pick the point y = 0 . 1 on the Y axis and draw a line parallel to the X axis through this point. This line will intersect the likelihood graph at two points. From each of these points draw a vertical line to the X axis. The interval on the X axis between the points where these vertical lines meet the X axis is the 10% likelihood interval. Observe that the point on the X axis with x = 0 . 3 is inside this interval. Hence the statement that the value = 0 . 30 is outside the 10% likelihood interval. is False. 2. The probability that is in the 15% likelihood interval is approximately 0.95. Answer: False We do not know anything about the distribution of . Hence we can not talk about the probability of being in any interval. In general, we cannot make a probability statement about a parameter unless we are in a bayesianin any interval....
