Hey There!:

Sample Mean = 4.4823

SD = 0.1859

Sample Size (n) = 7

Standard Error (SE) = SD/root(n) = 0.0703

alpha (a) = 1-0.99 = 0.01

t(a/2, n-1 ) =  3.7074

Margin of Error (ME) =  t(a/2,n-1)x SE = 0.2606

99% confidence interval is given by:

Sample Mean +/- (Margin of Error)

4.4823 +/- 0.2606 = (4.222 , 4.743)

Hope this helps!

tankabanditka [31]

Answer:

These two statements are correct:

A. Businesses and jobs rely most strongly on consumer demand.

B.Government regulation is necessary to stabilize the economy.

Explanation:

The first statement is correct because John Maynard Keynes that demand was the most important side of the economy, not supply. This is why his policies are sometimes referred to as "demand-side economics", while the policies of many of his detractors, such as Milton Friedman, are referred to as "supply-side economics".

The second statement is also correct because Keynes believed that a market economy was naturally subject to business cycles: cycles of boom and bust that could either benefit millions, or harm millions. Keynes thought that the government should regulate the economy in order to lessen the effect of those cycles.

Four hundred and eighty minutes of production time are available per day. The schedule calls for the production of 80 units per
BabaBlast [244]

Answer:

<em>The theoretical minimum number of workstations are five workstations</em>

Explanation:

Given the total time available per day = 480 minutes

the cycle time which is the time required or spent to produce a unit can be obtained as;

Cycle time = Total time / Demand per day

Cycle time = 480 / 80 = 6 minutes

hence 6 minutes is the cycle time  for one unit.

The theoretical number of stations can be calculated thus;

Theoretical number of stations = Time for one unit / Cycle time

= 30/6 = 5 workstations

<em>Therefore the theoretical minimum number of workstations are five workstations</em>
