Complete Question

A random sample of 300 circuits generated 13 defectives. a. Use the data to test

$H_o : p = 0.05$

Versus

$H_1 : p \ne 0.05$

Use α = 0.05. Find the P-value for the test

Answer:

The p-value is $p-value = 0.5949$

Step-by-step explanation:

From the question we are told that

The sample size is n = 300

The number of defective circuits is k = 13

Generally the sample proportion of defective circuits is mathematically represented as

$\^ p = \frac{k}{n}$

=> $\^ p = \frac{13}{300}$

=> $\^ p = 0.0433$

Generally the standard Error is mathematically represented as

$SE = \sqrt{\frac{p(1- p)}{n} }$

=> $SE = \sqrt{\frac{0.05(1- 0.05)}{300} }$

=> $SE = 0.0126$

Generally the test statistics is mathematically represented as

$z = \frac{\^ p - p }{SE}$

=> $z = \frac{0.0433 - 0.05 }{0.0126}$

=> $z = -0.5317$

From the z table the area under the normal curve to the left corresponding to -0.5317 is

$(P < -0.5317 ) = 0.29747$

Generally the p-value is mathematically represented as

$p-value = 2 * P(Z < -0.5317 )$

=> $p-value = 2 * 0.29747$

=> $p-value = 0.5949$

Umnica [9.8K]

Answer:

x=-2

Step-by-step explanation

1) Remove () and Rewrite

13x+13+2x=1/2x2(5x-7)

2) Collect Like Terms

15x+13=5x-7

3) Move Terms

15x-5x=-7-13

4) Divide Both Sides

10x=-20

ANSWER IS x=-2

Question:

Three students were working on 630,000÷700 in math class.

a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.

Determine which student found the correct quotient.

b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?

Answer:

a. Micah is correct

b.

$Expression = 63000 \div 700$

$Expression = 630000 \div 7000$

Step-by-step explanation:

Given

$Expression = 630000 \div 700$

$Desiree = 9000$

$Micah = 900$

Solving (a): Who is correct?

To do this, we first calculate the quotient of the expression.

$Expression = 630000 \div 700$

Divide 630000 by 700

$Quotient = 900$

Hence:

Micah is correct

Solving (b): What Delilah must have copied?

We have:

$Delilah = 90$

There are no options to pick from. So, we just need to work out expressions that equals 0.

Possible expressions are:

$Expression = 63000 \div 700$

$Expression = 630000 \div 7000$
