Answer: a. 2.8
Explanation:
Given : Population mean : 
Sample size : n= 49> 30 , the sample is a large sample we use z-test.
Sample mean = 
Standard deviation : 
The test statistic for population mean is given by :-
Hence, the value of the test statistic is 2.8
Answer:
it will help get into college.
Explanation:
a diploma doesn't open the doors to all jobs. also, if you want a higher pay for most jobs, you won't be able to get it with a diploma.
a diploma can open the doors to a college, though. which will help you further your education, and get a degree that can open the doors you need
Answer:
Number of vats used is 3
Explanation:
Number of pounds used per hour, D = 195 ÷ 8
= 24.375 pounds per hour
Cycle time, T = 2.25
Inefficiency factor, e = 0.19
Material held in vats, C = 25 pounds
Now,
Let, n be total number of vats
Thus,
n = 
on substituting the respective values, we get
n =
or
n = 2.413 ≈ 3
Number of vats used is 3 [since vats cannot be in fraction]
Answer:
The elasticity of supply for hot cocoa is 1.43.
(D) Supply in the market for coffee is less elastic than supply in the market for hot cocoa
Explanation:
Using the midpoint formula,
Elasticity of supply for hot cocoa = (change in quantity supplied/average quantity supplied) ÷ (change in price/average price)
change in quantity supplied = 101 - 31 = 70
average quantity supplied = (101+31)/2 = 66
70/66 = 1.06
change in price = 9.75 - 4.5 = 5.25
average price = (9.75+4.5)/2 = 7.125
5.25/7.125 = 0.74
Elasticity of supply for hot cocoa = 1.06 ÷ 0.74 = 1.43. The supply for hot cocoa is elastic because the elasticity of supply is greater than 1.
Elasticity of supply for coffee = (73 - 31)/(73+31)/2 ÷ 0.74 = 42/52 ÷ 0.74 = 0.81 ÷ 0.74 = 1.09. The supply for coffee is elastic because the elasticity of supply is greater than 1.
However, supply in the market for coffee is less elastic than supply in the market for hot cocoa because the elasticity of supply for coffee is less than that of hot coffee.
