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

Versus

Use α = 0.05. Find the P-value for the test
Answer:
The p-value is
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

=> 
=> 
Generally the standard Error is mathematically represented as

=> 
=> 
Generally the test statistics is mathematically represented as

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

Generally the p-value is mathematically represented as

Answer:
8x+40=56
Step-by-step explanation:
You have to distribute the 8
Then finish the rest of the problem
Answer:
$58.84375, rounded ≈ $58.84
Step-by-step explanation:
You can do 67.25 x 7/8 (use a calc if you are lazy) = 58.84375
I'm guessing you don't need to round so I'm going to add both real and rounded answers
