Consider the series ∑n=0[infinity](34)n. The first four terms in the sequence of partial sums for this series are 1, 3/4, 9/16, 27/64 . Enter a comma separated list of numbers (in order). The nth partial sum is Sn=1+3/4+(3/4)2+(3/4)3+⋯+(3/4)n= . Enter a closed-form expression for this sum. The sum of this geometric series is ∑n=0[infinity](34)n=limn→[infinity] (

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
