Answer:
C. H0: PL - PR = 0
Ha: PL - PR > 0
The null hypothesis for this case is that left-handed pitchers in a baseball league are not more likely to strike out batters than right-handed pitchers are. That is the proportion of at-bats resulting in a strikeout is significantly equal for both left-handed and right-handed pitchers.
H0: PL - PR = 0
The alternative hypothesis is that the proportion of at-bats resulting in a strikeout is significantly higher for left-handed pitchers
Ha: PL - PR > 0
PL - proportion of at-bats resulting in a strikeout for left-handed pitchers
PR - proportion of at-bats resulting in a strikeout for right-handed pitchers
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.

Answer:
For a square all the sides are equal and measure 27
Step-by-step explanation:
Answer:
f(x) = 
Step-by-step explanation:
Let the equation of the give cubic function is,
f(x) = p(x - a)(x - b)(x - c)
Here, a, b, c and d are the x-intercepts of the given graph.
Since, x-intercepts given in the graph are x = -5, 1 and 4,
Equation of the curve will be,
f(x) = p(x + 5)(x - 1)(x - 4)
Since, the graph of this function passes through (2, -2) also
-2 = p(2 + 5)(2 - 1)(2 - 4)
-2 = -p(14)
p = 
p = 
Therefore, equation will be,
f(x) = 
Area of triangle = 1/2 bh
60 = 1/2 (15) h
8 = h
Quadrilateral area = h x (b1 + b2)/2 = 8 x (15+9)/2 = 96 sq units
96 -60 = triangle BAD area = 36 sq units
Answer and Step-by-step explanation:
0 to the power of 4 is 0.
