Answer:
The required probability is 0.066807
Explanation:
Given,
σ = 220
μ = 1200
The probability that a random selection of computer which will have the price of at least $1,530 is computed as:
P (X ≥ 1530 ) = 1 - P (X ≤ 1530)
= 1 - P ( X - μ / σ)
= 1 - P ( 1530 - 1200 / 220)
= 1 - P ( z ≤ 1.5)
= 1 - 0.933193
= 0.066807
Note: This 0.933193 value is taken from the z table.

I hope my answer helps you
Answer:
Yes
Explanation:
From the given output
The Probability of getting 13 or more passed
when the reliability = 0.35. can be calculated as follows
=0.0258+0.0109+0.0039+.0012+0.0004 = 0.0422 ≈ 4.2%
Since the probability is less than the 5% level we will therefore reject the Null hypothesis
answer : YES
The correct option is B
<u>Explanation:</u>
In an economy, planned investment spending is always equal to planned saving. If actual saving falls short of (exceeds) planned saving, then actual investment falls short of (exceeds) planned investment.
That is the other part of the saving paradox. If an economy produces too much, such that saving is greater than planned investment, inventory will build up, giving signal to producers to reduce output, to restore equilibrium. Such investment scheme is suitable only to communist countries. Keynes has another investment theory in his liquidity story. But investment theories are equally a posterior.
Therefore, Option B is correct

agree with this
