Answer:
0.022
Step-by-step explanation:
Given that :
Population size = 25000
n = 500 ; p = 0.4
Size of random sample (n) = 500
5% of population size : 0.05 * 25000 = 1250
Distribution is normally distributed since n < 5% of population size
Hence, the mean of the distribution = p = 0.4
Standard deviation = √((pq) /n)
q = 1 - p ; q = 1 - 0. 4 = 0.6
Standard deviation = √((0.4 * 0.6) /500)
Standard deviation = 0.0219089
= 0.022
Answer:
D. The sequence diverges by oscillation.
Step-by-step explanation:
an = (-1.00000004)n
From root test
L = Lim n->infinity (|an|)(1/n)
==> L = Lim n->infinity (|-1.00000004n|)(1/n)
==> L = Lim n->infinity (|-1.00000004|n)(1/n)
==> L = Lim n->infinity |-1.00000004|
==> L = 1.00000004 > 1
Hence series diverges.
