Answer:
H0: p ≤ 0.50
Ha: p > 0.50
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
For the case above;
Let p represent the proportion of households in the city that gave a charitable donation in the past year
The null hypothesis is that the proportion of households in the city that gave a charitable donation in the past year is not more that 0.50
H0: p ≤ 0.50
The alternative hypothesis is that the proportion of households in the city that gave a charitable donation in the past year is more that 0.50
Ha: p > 0.50

Answer:
a) 800 square yards
b) 7200 square feet
Step-by-step explanation:
a) 40*20= 800 square yards
b) Each yard is 3 feet.
(40*3)*(20*3)=120*60=7200 square feet
Answer:
Explanation:
The figure labeled A cannot be because the cross and the line are not oriented in the same relative position as in X.
The figure labeled B cannot be because the line and the the image with the three lines are not oriented in the same relative position as in X.
You cannot tell about the figures labeled C because you do not see the images of the cross and the line.
The figure labeled E cannot be because the image with the three lines is not oriented in the same relative positiion with respect to the other two as in X.
You cannot tell about the figure labeled F because the image of the cross and with the three lines are not shown.
The figure labeled G is correct: you can just rotate the cube labeled X 90 degrees counterclockwise about a vertical axis that passes through the center of the cube and get the cube labeled G.
A. 8/$12=21/$x then cross multiply.
B. 1/$1.5
