An automatic machine is set to fill bags of dog food with exactly 25 pounds on average with a standard deviation of 0.5 pounds.

Rasek [7]

Answer:

Step-by-step explanation:

Given that an automatic machine is set to fill bags of dog food with exactly 25 pounds on average with a standard deviation of 0.5 pounds.

Sample size = n =100

x bar = 24.85 pounds

Sample std error = $\frac{\sigma}{\sqrt{n} } =0.05$

Hypotheses:

$H_0: x bar = 25\\H_a: x bar \neq 25$

(Two tailed test at 5% level)

Mean difference =0.15

Test statistic = mean diff/se = 3

Since population std dev is known z test can be used

p value =0.0000

Since p <0.05 we find that the bag does not contain exactly 25 pounds.

meriva

Answer:

16%

Step-by-step explanation:

The additional wage amount is $80.

The original wage amount is $500.

The ratio of the two is ...

$80/$500 = 0.16 = 16/100

To express that ratio as a percentage, multiply it by 100%.

0.16 × 100% = 16%

_____

It might help you to think of the percent sign (%) as a fancy way to write "per hundred" (/100). Of course, using your knowledge of place value, you know that 0.16 = sixteen hundredths = 16/100.

Realizing the meaning of the % sign, you can immediately write this as 16%.
