Answer: 300

Step-by-step explanation:

Given , An electronics retailer receives a shipment of 6,000CDs to distribute to its stores.

i.e, Total CD's he has now = 6,000

Also, a quality control manager inspects a random sample(S) of 40CD's , the number of defective(D) CD's are 2.

Then , the proportion of defective( D) CD's = $\dfrac{D}{S}=\dfrac{2}{40}=0.05$

Now , the number of CDs in the shipment are likely to be defective = ( Total CD's) x (proportion of defective CD's)

= 6000 x 0.05

=300

Hence, the number of CDs in the shipment are likely to be defective =300

So the formula for the volume of a sphere is 4/3 * (π * r³)

V = 4/3 * (π * 6³)

V = 4/3 * (π * 216)

V = 4/3 * 678.24

V = 904.78

Answer:

(c) 11

Step-by-step explanation:

As x goes up by 1, f(x) goes up by 2. The next line of the chart would be ...

x = 4+1 = 5; f(x) = 9+2 = 11

The appropriate choice is f(5) = 11.

Assume, for the sake of this question, that the data were collected through a well-designed, well-implemented random sampling me

Answer:

Since the pvalue of the test is 0.2743 > 0.1, the threshold probably was met.

Step-by-step explanation:

The widget manufacturing company had established a threshold of 60% preferring the proposed new widget to move forward with producing the new widgets.

This means that at the null hypothesis we test if the proportion is at least 60%, that is:

$H_{0}: p \geq 0.6$
