Answer:
Test statistic Z = p diff/std error = 2.3333
p value one tailed = 0.009815
Step-by-step explanation:
Given that in a survey conducted by a website, employers were asked if they had ever sent an employee home because they were dressed inappropriately.
Sample size n = 2755
Sample favourable x = 967
Sample proportion p = 
(right tailed test at 5% significance level)
p difference = 0.0210
Standard error assuming H0 is true is 
Test statistic Z = p diff/std error = 2.3333
p value one tailed = 0.009815
Since p <0.05 we reject null hypothesis.
The area of a square is (side)².
If the area is 128m², then the side is (√128) meters. (That's 8√2.)
The diagonal is the hypotenuse of the right triangle you get
if you slice the square in half along the diagonal. Its length is
given in the words of Old Pythagoras:
c² = a² + b²
'a' and 'b' are sides of the square, so
c² = (√128)² + (√128)²
= 2 (√128)²
c = √ (2 x 128) = √256 = 16 meters .
Answer:
8.75
Step-by-step explanation:
2*2+2.25+2.5=4+4.75=8.75
*assuming the smudged fraction is 1/4
b since it is equal and graeter than -7
For this case we have the following amount of liquid:
2.5 oz.
The amount of liquid needed is:
3 oz.
Therefore, the amount of fluid needed is:
3oz - 2.5oz = 0.5oz
Answer:
b. no, hildy did not get a reasonable amount of liquid because she only needed 0.5 oz (3 - 2.5 = 0.5).
