Answer: 0.030
Step-by-step explanation:
Given: The percent of the items produced by a machine are defective :
The percent of the items produced by machine which are not defective:
Sample size : n = 100
Now, the standard error of the proportion is given by :-

Hence, the the standard error of the distribution of the sample proportions=0.030
To solve this all we need to do is multiply.
Since 1 kg is for $8, then we will multiply to see how much 16 kg would be for.
16 × 8 = 128
So, 16 kg is for $128.

Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0): 
Alternative hypothesis (H1): 
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no
