Given:
n = 4000, sample size
p = 16% = 0.16, the proportionof theose who watch60 minnures.
Confidence interval (CI) = 95%
The z* parameter is 1.96 for 95% CI, so the confidence interval is

That is
0.16 +/- 1.96*√[(0.16*0.81)/4000]
= 0.16 +/- 0.114
= (0.1486, 0.1714)
Answer:
The 95% confidence interval is approximately (15%, 17%) or 15% ≤ p ≤ 17%.
Note:
To correct for the fact that we are using a discrete distribution to match a continuous distribution, it is customary to subtract 0.5/n from the lower limit and to add it to the upper limit.
If this correction is applied, the 95% confidence interval becomes
(0.1486-0.5/4000, 0.1714+0.5/4000)
= (0.1485, 0.1715)
or
15% ≤ p ≤ 17%
The correction does not affect the result in a significant way.
As the price of beef increases, consumption, which means that for the demand of beef , there is an inverse relationship between price and consumption.
Explanation:
We know that there is an inverse relationship between price and demand. If the price increases the demand for that commodity falls. On the other hand if the price decreases the demand for that commodity increases.
If the price of beef increases that leads to less demand for the consumption of beef on the other hand if the price of beef decreases which will lead to increase in the demand for the consumption of beef.
Answer:
The present value of security is $2300
Explanation:
The value or price of the perpetuity today is calculated by dividing the constant cash flow it provides per period by the interest rate or the rate of return (r). Thus the price of this perpetuity according to the formula will be,
Value of perpetuity = Cash flow / r
Value of perpetuity = 115 / 0.05
Value of perpetuity = $2300
Answer:
The correct option is B
Explanation:
According to income tax laws, an individual will pay mess capital gains tax when his basis in an asset is higher. From the example, John has a personal residence and to increase his basis, he needs to think of what to add to the residence such that the selling price would increase and thus capital gain tax will reduce. From the option, the best and likely thing that would increase the basis of his asset (the house) and lead to an increase selling price is adding a new garage.
I think the correct answer is “Money supply”
