Based on the percentage of readers who own a particular make of the car and the random sample, we can infer that there is sufficient evidence at a 0.02 level to support the executive claim.
<h3>What is the evidence to support the executive's claim?</h3>
The hypothesis is:
Null hypothesis : P = 0.55
Alternate hypothesis : P ≠ 0.55
We then need to find the test statistic:
= (Probability found by marketing executive - Probability from publisher) / √( (Probability from publisher x (1 - Probability from publisher))/ number of people sampled
= (0.46 - 0.55) / √(( 0.55 x ( 1 - 0.55)) / 200
= -2.56
Using this z value as the test statistic, perform a two-tailed test to show:
= P( Z < -2.56) + P(Z > 2.56)
= 0.0052 + 0.0052
= 0.0104
The p-value is 0.0104 which is less than the significance level of 0.02. This means that we reject the null hypothesis.
The Marketing executive was correct.

The federal reserve account is the central bank of the United States of America. It is an independent bank in a sense that it does not need the approval of the President or any government authority to forego with their daily transactions. Only institutions have accounts in the federal reserves like commercial banks. An individual cannot access one.
Answer:
An implied agreement is based on a formal agreement.
Explanation:
A contract can be defined as an agreement between two or more parties (group of people) which gives rise to a mutual legal obligation or enforceable by law.
There are different types of contract in business and these includes: fixed-price contract, cost-plus contract, bilateral contract, implied contract, unilateral contract, adhesion contract, unconscionable contract, option contract, express contract, executory contract, etc.
Mutual assent is a legal term which represents an agreement by both parties to a contract. When two parties to a contract both have an understanding of the parameters, terms and conditions surrounding a contract, it ultimately implies that they are in agreement; this is generally referred to as mutual assent.
Simply stated, mutual assent connotes agreement, acceptance and consent to a contract by both parties.
An implied contract can be defined as an informal contract that exists based on an assumption or understanding between two or more parties, rather than on terms that are formally and specifically defined.
This ultimately implies that, an implied agreement is not based on a formal agreement but on assumptions or understanding between the parties involved.
Answer:
From the attached excel file, we havee:
Revenue and spending income from operations variance = $4,566 Favorable
Activity income from operations variance = -$5,860 Unfavorable
Explanation:
Note: See part a of the attached excel file for the flexible budget performance report that shows both revenue and spending variances and activity variances for September.
Also Note: See parts b and c of the attached excel file for the calculations of revenue and spending variances and activity variances respectively for September.
Answer:
The speed of the car is 67.77 m/s and it is moving away from the observer.
Explanation:
The apparent frequency is given as
![f' = f\dfrac{ [v - vo]}{ [v - vs]}](https://tex.z-dn.net/?f=f%27%20%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D)
Here
o is the observer
s is the source which is car
v is the speed of sound = 343 m/s
f = true frequency emitted by the car (when stationary)
f ' = 0.835 f
so
![f' = f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 f= f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 = \dfrac{ [343 - 0]}{ [343 - vs]}\\0.835=\frac{343}{343-x}\\x=-67.77 m/s](https://tex.z-dn.net/?f=f%27%20%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D%5C%5C0.835%20f%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D%5C%5C0.835%20%3D%20%5Cdfrac%7B%20%5B343%20-%200%5D%7D%7B%20%5B343%20-%20vs%5D%7D%5C%5C0.835%3D%5Cfrac%7B343%7D%7B343-x%7D%5C%5Cx%3D-67.77%20m%2Fs)
The speed of the car is 67.77 m/s and it is moving away from the observer.
