What is the probability that a value falls in the interval μ ± 2σ, that computes the probability P(-2 < Z < 2). Round to f
our decimals and use leading zeros
1 answer:
Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.

Since both 2 and 5 are prime numbers, there are no multiples for the fraction 2/5.
They made 3000$ in profit 500x100=50k
470x100=47k
47,000-50000=3000
Interest = PRT /100
500 = 2000*2.5*T / 100
5000T = 50,000
T = 50,000 / 5000 = 10 years
