Let X be a random variable corresponding to the number of trials k needed to soccertimes. Suppose the probability of success for each trial ispand thateach of the trials are independent.1. If the number of trials needed isk, then we must succeed on the kth trial. How many possible ways can we arrange the previousr−1 successes

which of the following sets of data would produce the largest value for an independent-measures t statistic? the two sample means are 10 and 20 with variances of 20 and 25 the two sample means are 10 and 20 with variances of 120 and 125 the two sample means are 10 and 12 with sample variances of 20 and 25 the two sample means are 10 and 12 with variances of 120 and 125
