Answer:

Because the test statistic is less than the critical value, we can reject the null hypothesis  and conclude that the population correlation coefficient is less than zero.

Explanation:

Because the question is based on the hypothesis test of the significance of the correlation coefficient to decide whether the linear relationship in the sample data is strong enough to use to model the relationship in the population. If the tests concludes that the correlation coefficient is not significantly different from zero, it means that the correlation coefficient is not significant.

Meena Chavan Corp's computer chip production process yields DRAM chips with an average life of 2,000 hours and s = 120 hours. Th
AnnZ [28]

Answer: a.)Cp= 1.25 ; b.) process is very capable ; c.) 0.83 ; d.) does not meet requires specification.

Explanation:

Given the following ;

Average chip life = 2000 hours

Standard deviation = 120 hours

Tolerance upper specification limit = 2600 hours

Tolerance lower specification limit = 1700 hours

A.) process capability ratio (Cp) :

Cp = (Upper specification limit - Lower specification limit) ÷ 6(standard deviation)

Cp = (2600 - 1700) ÷ (6 × 120)

Cp = 900 ÷ 720 = 1.25

B.) Capability ratio of 1.25 demonstrated that it is very capable.

C.) process capability ratio index(Cpk) :

Mean (X) = (Upper specification limit(US) - Lower specification limit(LCL))

Mean(X) = 2000

Lower Cpk = (X - LSL) ÷ 3(standard deviation)

Lower Cpk = (2000 - 1700) ÷ (3 × 120)

Lower Cpk = 300 ÷ 360 = 0.83

Upper Cpk = (USL - X) ÷ (3 × Standard deviation)

Upper Cpk = (2600 - 2000) ÷(3×120)

Upper Cpk = 600 ÷ 360 = 1.67

Cpk = Minimum_of (Upper Cpk, Lower Cpk)

Cpk = Minimum_of (1.67,0.83)

Cpk = 0.83

D.) Cpk < 1.0, shows that it does not meet required specification.

As the economy declines into recession, the collection of personal income tax revenues automatically falls. this phenomenon best
abruzzese [7]

This phenomenon best illustrates how a progressive income-tax system serves as an automatic stabilizer for the economy.

<h3>What is an automatic stabilizer?</h3>

Automatic stabilizers are stabilizers that adjust the economy automatically without the intervention of external agents . Examples include progressive tax and transfer payments. A progressive tax is a tax structure where those who earn higher income are taxed more and those that earn less pay less amount of tax.

In an expansion, progressive tax increases the tax paid and this reduces disposable income. In a recession, tax paid is reduced and this increases disposable income

Here are the options:

increases crowding out in the economy

decreases real interest rates in the economy

offsets the timing problem for fiscal policy

Serves as an automatic stabiler for the economy

Explanation:

a) Data and Calculations:

Selling price $ 128

Units in beginning inventory 0

Units produced 9,150

Units sold         8,750

Units in ending inventory 400

Variable costs per unit:

Direct materials $ 22

Direct labor $ 64

Variable manufacturing overhead $ 10

Variable selling and administrative expense $ 14

Fixed costs:

Fixed manufacturing overhead $ 137,250

Fixed selling and administrative expense $ 9,200

Direct materials                               $ 22

Direct labor                                     $ 64

Variable manufacturing overhead $ 10

Variable costs per unit                   $ 96 * 9,150 = $878,400

Fixed manufacturing overhead                             $ 137,250

Total production cost                                           $1,015,650

Product cost per unit = $111

Cost of goods sold = $971,250 ($111 * 8,750)

Period costs:

Variable selling and administrative expense $ 14 * 8,750 = $122,500

Fixed selling and administrative expense $ 9,200
