Answer:
(b) H0: p = 0.5; Ha: p > 0.5
Step-by-step explanation:
p represents the population proportion.
A null hypothesis is a statement from the population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.
An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
A point in quadrant 4 would have the "x" value positive and the "y" value negative.
So, it would equal (+, -)

Umm... where are the questions so I could answer them
Answer:
23
Step-by-step explanation:
100 is the exterior angle.
( 2x + 3 ) and 51 are interior angles.
Formula : -
Exterior angles = Sum of two interior angles.
100 = 2x + 3 + 51
100 = 2x + 54
2x = 100 - 54
2x = 46
x = 46 / 2
x = 23
