Answer:
The statements that are true about a hypothesis test for two proportions are:
I. It estimates the common value of p1 and p2 under the assumption of equal proportions.
II. It is obtained by averaging the two sample proportions 1 and 2.
Step-by-step explanation:
We use the two sample proportion z-test to determine whether the proportions of the two groups differ. This test calculates the range of values that is likely to include the differences between the sample proportions of p1 and p2.

A manager is going to purchase new processing equipment and must decide on the number of spare parts to order with the new equipment. The spares cost $179 each, and any unused spares will have an expected salvage value of $49 each. The probability of usage can be described by this distribution: Number 0 1 2 3 Probability .05 .60 .20 .15 Click here for the Excel Data File If a part fails and a spare is not available, 2 days will be needed to obtain a replacement and install it. The cost for idle equipment is $640 per day. What quantity of spares should be ordered
Answers
Answer:
service level is 90.78% ( it falls on cumulative probability of 1.00 or 100%)
Therefore the quantity of spares that should be ordered is 3
Step-by-step explanation:
Given that;
spares cost = $179 each
salvage value = $49 each
distribution of the probability of usage;
Number Probability cumulative Probability
0 0.05 0.05
1 0.60 0.65
2 0.20 0.85
3 0.15 1.00
Now
the cost of stock-out (underestimation) Cu
= $640 per day × 2 days = $1,280
the cost of excess inventory (overestimation) Co
= Unit cost - salvage value = $179 - $49 = $130
Therefore Service Level = Cu / ( Cu + Co )
we substitute
Service Level = $1,280 / ( $1,280 + $130 )
= $1,280 / $1410
= 0.9078 or 90.78%
so service level is 90.78% ( it falls on cumulative probability of 1.00 0r 100%)
Therefore the quantity of spares that should be ordered is 3

Denise lives in a two-story house with a basement. The first
story of the house is at ground level. The basement floor is at
an elevation of −10.5 feet and the second story floor has an
elevation of 121 feet. Use the absolute value of each elevation 4
to find the distance between the basement floor and the second story floor.
Answers
Answer:
Distance = 110.5 cm
Step-by-step explanation:
It is given that,
The basement floor is at an elevation of −10.5 feet
The second story floor has an elevation of 121 feet.
We need to find the distance between the basement floor and the second story floor.
Distance = -10.5 + 121
= 110.5 feet
So, the distance between the basement floor and the second story floor is 110.5 cm.

Sin(0)= cos(6) what is the value of 0?
Answers
We need to find Ο for : sin(Ο)= cos(6)
We know that:
cos θ =sin (90 - θ), so if we call θ = 6 then O will be:
O = 90 - θ
O = 90 - 6
O = 84The value of 0 is 84.
Given that,
Sin(0)= cos(6).
Based on the above information, the calculation is as follows:
cos θ =sin (90 - θ),
So in the case when θ = 6
So, O will be
O = 90 - θ
O = 90 - 6
O = 84

Now we can write a proportion relating right-side transversal segments to left-side transversal segments:
?/6 = 6/4
? = 6(6/4) = 36/4 = 9
The missing length is 9 units.
