Complete Question

The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test $H_o : p = 0.28$ vs $H a : p < 0.28$ when the sample has n 900 , and $\^ p = 0.216$ with $SE= 0.01$ . Find the value of the standardized z -test statistic. Round your answer to two decimal places.

Answer:

The value is $z = -6.40$

Step-by-step explanation:

Generally the standardized test statistics is mathematically represented as

$z = \frac{\^ p - p }{ SE }$

=> $z = \frac{0.216 - 0.28 }{ 0.01 }$

=> $z = \frac{0.216 - 0.28 }{ 0.01 }$

=> $z = -6.40$

I need help on #10. very confused

RideAnS [48]

Step-by-step explanation:

$\displaystyle f'(x) = \lim_{h \to 0} \dfrac{f(x + h) - f(x)}{h}$

$\:\:\:\:\:\displaystyle = \lim_{h \to 0} \dfrac{(x+h)^2 -7 -(x^2 - 7)}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{(x^2 +2hx + h^2 -7) - (x^2 -7)}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{2hx + h^2}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} (2x +h)$

$\:\:\:\:\: \displaystyle= 2x$

What is X in this equation?<br> 3x+55=9x-5<br><br>Please Explain.

klasskru [66]

Answer:

x = 10

Step-by-step explanation:

3x + 55 = 9x - 5 (add 5 to both sides)

3x + 55 + 5 = 9x - 5 + 5

3x + 60 = 9x (subtract 3x from both sides)

60 = 9x - 3x

60 = 6x (rearrange)

6x = 60 (divide both sides by 6)

x = 60/6

x = 10

A pair of desiner sneakers was bought for $120. Since they were bought their price had increased by 15%. What is the new price

kodGreya [7K]

The base price is $120. 15% in decimal form is 0.15, to get 15% of 120 you multiply the decimal form of 15% by 120.
0.15 * 120 = 18
Since the price increased by 15 percent, and $18 is 15% of 120, we add 18 to 120, so the answer is

$138
