A plot of land is valued at $18,000.Land tax is charged at the rate of 0.70 per $100. What is the total amount of tax paid for t
Vladimir [108]

Answer:

<em>The total amount of tax paid for the land was $126</em>

Step-by-step explanation:

<u>Proportions</u>

The land tax charged is 0.7 per each $100 of the land value. For easy calculations, we find the ratio or proportion to be applied to the value of the land as:

0.7 / 100 =0.007

This factor can be used to obtain the tax charged for a given value of the land.

The plot of land of the question is valued at $18,000.

The tax charged is, then:

0.007*18,000 = 126

The total amount of tax paid for the land was $126

Nitella [24]
The hypothesis testing for this problem is:
a. The hypothesis for this problem are:
Null: H0: μ=6
Alternative: Ha: μ≠6
 
b. Test
T-statistics = (6.08 - 6) / 0.44* √(121) = 2
 
c. P value = 0.047759
 
Since our p-value is smaller than the significant level of 0.05, we can say that we reject the null hypothesis.

Conclusion: there is enough evidence to say lathe is not in perfect adjustment.

A survey of households in a small town showed that in 850 of 1,200 sampled households, at least one member attended a town meeti
Iteru [2.4K]

Answer:

Hence the confidence interval is ( 0.6745, 0.7422).

Step-by-step explanation:

Now the given are  

Sample size = n = 1200  

x = 850  

Sample proportion is  

\hat{p}=\frac{x}{n}=\frac{850}{1200}=0.7083  

We have to construct 99% confidence interval for the population proportion.  

Formula Used:  

(\hat{p}-E , \hat{p}+E)  

Here E is a margin of error.  

E =Zc\times\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}  

Zc = 2.58  

E =2.58\times\sqrt{\frac{0.7083*(1-0.7083)}{1200}}\\\\E=2.58\times\sqrt{0.000172}=0.0339  

So confidence interval is ( 0.7083 - 0.0339 , 0.7083 + 0.0339)

                                            = ( 0.6745 , 0.7422).
