Answer:
comparison of two sample proportions independent
Step-by-step explanation:
Given that the percent of managers at High Tech Inc. that pay over $8 per day for lunch is the same as the percent of technicians.
The data can be given as follows:
The samples are as follows
Managers 60 149
Who paid >8 46 98
Hence we compare sample proportions here.
The appropriate test would be
comparison of two sample proportions independent

Answer:
Step-by-step explanation:
Product = -3
Sum = -2
Factors = -3 , 1
y² - 2y - 3 = y² + y - 3y - 3
= y( y + 1) - 3(y + 1)
= (y +1) (y - 3)
Answer:
x=y^2/2 - 3/2
Step-by-step explanation:
b. percentage, probability, proportion
c. critical value, percentage, proportion
d. critical value, percentage, probability
Answer:
Step-by-step explanation:
The diameter of the circle is twice the radius, so the diameter of the circle is 2 x 12 inches = 24 inches.
To find the area of the circle, we can use the formula A = πr^2, where A is the area of the circle and r is the radius.
So, for this circle, A = π(12 inches)^2 = 144π square inches.
Therefore, the diameter of the circle is 24 inches, the formula to find the area of the circle is A = πr^2, and the area of the circle is 144π square inches.
Answer: 144 pie square inches!
Step-by-step explanation:
1st blank : is 24 square inches since the radius which is half the diameter is 12 square inches we can easily know that the diameter would be 24 square inches!
2nd blank : pie r squared is the formula! for all areas of the circles! the total length in other words the circumference of the circle would be 2 pie r basically multiplying 2 and pie and the radius.
3rd blank : the area of the circle is 144 pie (square inches)!
Answer:
24.78%
Step-by-step explanation:
Initial price = $230
Final price = $287
change in price = final price - initial price
= 287 - 230
= $57
Percent change
= (change in price / initial price) x 100%
= (57 / 230) x 100%
= 24.78%
