melomori [17]

Answer: 0.0158

Step-by-step explanation:

Given : The data for the United States is that out of 1,000 sampled, 470 indicated yes, they felt political news was reported fairly.

According to the given information we have,

Sample size : n= 1000

Sample proportion: \hat{p}=\dfrac{470}{1000}=0.47

The standard error for proportion is given by :-

S.E.=\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

S.E.=\sqrt{\dfrac{0.47(1-0.47)}{1000}}

S.E.=\sqrt{0.0002491}

S.E.=0.0157829021412\approx0.0158

[Rounded to the nearest four decimal places.]

Hence, the standard error for the confidence interval = 0.0158

If p represents the original price, which of the following expressions could be used to calculate the sale price of a shirt that
dezoksy [38]

Answer:

C & D

Step-by-step explanation:

You can do these two ways. You can multiply the cost of the the shirt by 15% (.15 as a decimal.) and then subtract that answer from the original price of the shirt to get the sales price of the shirt.

You can also multiply the price of the shirt by 85% (.85 as a decimal) and that will give you the sales price without having to subtract. 15% + 85% = 100%, so 85% represents the sales price of the shirt.

Anyway, since you multiply, you can eliminate choice A & B.

Since the direction in the question says to select all that apply, I would check both C & D.

C is the equation of the first way I talked about- Price - 15% * price

C       p - 0.15p

D is the equation of the second way I talked about. Price times 85%

D            0.85p
