Tests for divergence of convergence
4)
a) Use the ratio test to deteremine whether the series converges
or diverges
infinite sum (4^n)/(n!)
n = 1
b) Use the root test to determine whether the series converges
or diverges
infinite sum ((2n + 1)/7n + 4) ^ 2n
n = 1

Important Rules:
1.) You may not use loop constructs like while/for/sum. If used,
your answer will get a zero.
2.) If the instructions state something must be recursive, you will
recieve a zero if it is not recursive.
Recursive helper functions are allowed (the main function not being
recursive).
3.) You may not use the set! command. If used, your answer will get
a...
Find the P- value for the hypothesis test with the standardized
test statistic z. Decide whether to reject H0 for the level of
significance α. Two- tailed test z = 1.95 α = 0.05
