The manager of the Danvers-Hilton Resort Hotel stated that the mean guest bill for a weekend is $600 or less. A member of the ho

BlackZzzverrR [31]

Answer:

a) H₀= The mean guest bill for a weekend is $600 or less.

Hₐ= The mean guest bill for a weekend is more than $600.

b) We can conclude that the manager's claim is wrong.

c) We cannot conclude that the manager's claim is wrong. On the contrary, it is right.

Step-by-step explanation:

a) We have to state the null hypothesis and the alternate hypothesis.

The null hypothesis is the hypothesis we plan to discredit or to prove it's false. On the other hand, the alternative hypothesis is what we expect or hope to be true.

In this case, the accountant wants to prove the manager's claim that the total charges for guests have been increasing, so the mean guest bill for a weekend would be more than $600. What the accountant needs to discredit is that the mean guest bill for the weekend is $600 or less.

Considering what we just stated in the previous paragraph we would have:

The null hypothesis <u>H₀= The mean guest bill for a weekend is $600 or less.</u>

The alternative hypothesis<u> Hₐ= The mean guest bill for a weekend is more than $600.</u>

b) When H₀ cannot be rejected, then there's no evidence supporting the manager's claim, meaning that the guest bills have not been increasing in recent month. So the manager's claim is likely wrong

c) If H₀ is rejected, then we can conclude that the manager's claim is likely right and the total charges for guest bills have been increasing.

A principal amount of $3000 is invested for 3 years at 4% compounded semi-annually. Use the compound interest formula to determi

andreev551 [17]

The $378.49 was earned on the investment if the principal amount of $3000 is invested for 3 years at 4% compounded semi-annually.

<h3>What is compound interest?</h3>

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

$\rm A = P(1+\dfrac{r}{n})^{nt}$

Where A = Final amount

P = Principal amount

r = annual rate of interest

n = how many times interest is compounded per year

t = How long the money is deposited or borrowed (in years)

Here,

P = $3000

r = 4% = 0.04

n = 2

t = 3 years

After plugging all the values in the formula:

$\rm A = 3000(1+\dfrac{0.04}{2})^{2\times 3}$

After solving:

A = $3,378.49

I = A - P = 3,378.49 - 3000 = $378.49

Thus, the $378.49 was earned on the investment if the principal amount of $3000 is invested for 3 years at 4% compounded semi-annually.

Cup o’ Coffee buys its coffee for $1.25 a cup. The coffee shop then sells each cup for $3.75. What is the percent markup for a c

oee [108]

Answer:

47%

Step-by-step explanation: 375 × .125 = .046875

rounding up, 5 keeps the 7 as is, 7 is greater than 5, therefore the 8, becomes a 9, 9 is greater than 5, so the 6 becomes a 7, .047.

move the decimal three digits to the left and you get, 47%.
