A principal of $2000 is placed in a savings account at 3% per annum compounded annually. How much is in the account after one ye
natita [175]

Answer:

Step-by-step explanation:

After one year

A=p(1+r/n)^nt

=2000(1+0.03/12)^12*1

=2000(1+0.0025)^12

=2000(1.0025)^12

=2000(1.0304)

=$2060.8

After two-years

A=p(1+r/n)^nt

=2060.8(1+0.03/12)^12*2

=2060.8(1+0.0025)^24

=2060.8(1.0025)^24

=2060.8(1.0618)

=$2188.157

After three years

A=p(1+r/n)^nt

=2188.157(1+0.03/12)^12*3

=2188.157(1+0.0025)^36

=2188.157(1.0025)^36

=2188.157(1.0941)

=$2394.063

The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a mean temperature
Bingel [31]

Answer:

There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees

Step-by-step explanation:

Given : Claim : The mean temperature of the refrigerators is different from 45 degrees

To Find :Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null​ hypothesis, state the conclusion in nontechnical terms.

Solution:

Claim : The mean temperature of the refrigerators is different from 45 degrees

So, Null hypothesis : H_0:\mu = 45

Alternate hypothesis :   H_a:\mu \neq 45

We are given that the conclusion is to reject the null​ hypothesis.

So, we can say that the claim is true that mean temperature is different from 45 degrees.

There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
