Answer:
The null hypothesis is
Alternate hypothesis is
Step-by-step explanation:
Consider the provided information.
A study found that, in 2005, 12.5% of U.S. workers belonged to unions.
Suppose a sample of 400 U.S. workers is collected in 2006 to determine whether union efforts to organize have increased union membership.
Here we just need to formulate the hypotheses.
It is given that:
n=400 and 12.5% of U.S. workers belonged to unions.
12.5% can be written as:
12.5/100=0.125
The Null hypothesis: The workers belonging to unions ≤ 0.125
Alternate hypothesis: The workers belonging to unions is > 0.125
This can be written as:
So, the null hypothesis is
Alternate hypothesis is
Given:
13% calories from added sugar
270 calories
To get the total amount of calories, we need to divide the part by its corresponding percentage.
270 calories ÷ 13% = 2,076.92 calories.
=2,076.90 CALORIES
Answer:
75%
Step-by-step explanation:
There is 1 whisker and quartiles 1-3 so:
25%+25%+25%=75%
Answer:
THE VALUE OF x = 20 ;
Step-by-step explanation:
Since the quadrilateral PQRS is parallelogram,
Opposite sides are congruent , i.e QR =PS & PQ = RS
NOW EQUATING THE SIDES,
⇒ 4x - 15 = 3x +5
⇒ x = 20
Answer:
Darnell used 4 of the pages.
Step-by-step explanation:
6 times 6 is 36, and 9 goes into 36 4 times. Therefore, if Darnell put 9 cards on every page, he used 4 pages.
