Answer: It is sufficient evidence that it will reject the null hypothesis.
Step-by-step explanation:
Since we have given that
Number of players of baseball games = 162
Number of games won = 97
So,
Hypothesis:
So, test statistic would be
And the p-value = 0.006 at z=2.514.
Since p-value < α = 0.10 significance level.
Hence, it is sufficient evidence that it will reject the null hypothesis.
Answer:
B.) 113°
Step-by-step explanation:
In the isosceles trapezoid, angles T and S are congruent. Find the value of x:
Subtract 4x from both sides:
Add 38 to both sides:
Divide both sides by 3:
x is equal to 15. Now substitute the value of x into the one of the expressions:
or
The angles T and S are 67°.
The angles of a trapezoid will always add up to a total of 360°, so add the angles T and S:
Subtract their total from 360:
The total of the angles Q and R is 226°. Since this is an isosceles trapezoid, those two angles are also congruent. Divide the value by 2:
Angle R is 113°.
Done.
