Answer:
Step-by-step explanation:
Given : In a study investigating a link between walking and improved health, researchers reported that adults walked an average of 873 minutes in the past month for the purpose of health or recreation.
Claim : The true average number of minutes in the past month that adults walked for the purpose of health or recreation is lower than 873 minutes.
i.e. 
We know that the null hypothesis contains equal sign , then the set of hypothesis for the given situation will be :-
Answer:
FALSE
Step-by-step explanation:
and
are not equal.
If we assign numbers to both variables, for example x=1 and y = 2, we get:
. This shows that .5 is not equal to 2, therefore a fraction of something (x) is not always equal to a fraction of another something.
Answer:
The figure is NOT unique.
Imagine the following quadrilaterals:
Rectangle
Square
We know that:
Both quadrilaterals have at least two right angles.
However, they are not unique because they depend on the lengths of their sides.
Step-by-step explanation:
To construct a quadrilateral uniquely, five measurements are required. A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given or if the lengths of its three sides and two diagonals are given.
Just given two angles we cannot construct a unique quadrilateral. There may be an infinite number of quadrilaterals having atleast two right angles
Examples:
All squares with varying sides
All trapezoids with two right angles
All rectangles with different dimensions
and so on.
Answer is
No.
