Christopher deposited $1 in a savings account earning 10% interest, compounded annually.

Mathematics
1 answer:
kobusy [5.1K]4 years ago
6 0

Answer:

<u>To the nearest cent, Christopher will earn $ 0.13 in 3 years</u>

Step-by-step explanation:

Let's recall that the formula of the compounded interest is:

A = P * (1 + r/n)^nt, where

A = Future value

P = Initial deposit

r = Interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Replacing with the values we know:

A = P * (1 + r/n)^n

A = 1 * (1 + 0.1/1) ³°¹

A = 1 * 1.1³

A = 1 * 1.1331

A = 1.13

Interest = Future value - Initial deposit

Interest = 1.13 - 1

<u>Interest = 0.13</u>

Consider the one-sided confidence interval expressions for the mean of a normal population. Round your answers to 2 decimal plac
ser-zykov [4K]

Answer: a) 0.84  b) 0.67  c) 1.28

Step-by-step explanation:

Using the standard normal distribution table for z-value , we have

(a) The value of z_{\alpha} would result in a 80% one-sided confidence interval : z_{(1-0.80)}=z_{0.20}=0.8416\approx0.84

(b) The value of z_{\alpha} would result in a 85% one-sided confidence interval : z_{(1-0.85)}=z_{0.25}=0.6744897\approx0.67

(c) The value of z_{\alpha} would result in a 90% one-sided confidence interval : z_{(1-0.90)}=z_{0.10}=1.2815515\approx1.28
