1(2). TRUE/FALSE: For a hypothesis test, using a xed sample, increase the value of signicance level a, will decrease the probability of type II error. c 2(2). TRUE/FALSE: The t distribution curve with degree of freedom '0 = 15 is closer to standard normal curve than the t distribution curve with degree of freedom U = 10. c 0 3(2). TRUE/FALSE: For a standard normal distribution, the 95th percentile is less than the critical value 20.1 0 4(2). TRUE/FALSE: Two events A, B are independent, hence they are disjoint
