A random sample of 300 circuits generated 13 defectives. Use the data to test the hypothesis Upper H Subscript 0 Baseline colon

____ [38]

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

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

=> $p-value = 2 * 0.29747$

=> $p-value = 0.5949$

Evaluate the polynomial when a. x = 0 and b. X = - 1. x^2 - 8x - 7

jeka57 [31]

Answer:

(a) -7, (b) 2

Step-by-step explanation:

a) When x = 0,

=> x² - 8x - 7

=> (0)² - 8(0) - 7

=> 0 - 0 - 7

=> - 7

b) When x = -1,

=> x² - 8x - 7

=> (-1)² - 8(-1) - 7

=> 1 + 8 - 7

=> 9 - 7

=> 2

Hope it helps.

One half times (four plus eight)

liraira [26]

Answer:

Step-by-step explanation:

one half times (four plus eight)

Writing mathematically

1½ ( 4+8)

Using BODMAS

we'll take the bracket first

1½ × 12

Change 1½ to improper fraction = 3/2

3/2 × 12 = 3×6

= 18
