Answer:
The 95% confidence interval would be given by (0.027;0.093)
A. 0.027 to 0.093.
Step-by-step explanation:
Notation and definitions
number of defective.
random sample taken
estimated proportion of defectives
true population proportion of defectives
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The population proportion have the following distribution
Solution to the problem
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by 
and 
. And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
If we replace the values obtained we got:
The 95% confidence interval would be given by (0.027;0.093)
A. 0.027 to 0.093.
Answer:
martphones are a type of handheld computer that do not need input, output, processing, or storage.
Step-by-step explanation:
im a boy so i looked it up on google here is what i found.
Use a wide-toothed comb, wash your hair in sections, dont wash your hair every day he tighter your curls, the less frequently your hair may need to be washed. If you do need to wash your hair more frequently, you can use a dry shampoo in between those washes.
Don’t “wash, rinse, and repeat”--that style advice may work for people with straighter hair, but it’s no good for those with curly hair. When you wash your hair, only wash it once, but make sure that it’s a thorough wash so that all dirt and oil is removed from your hair.
If needed, you can wash your hair with conditioner (called “co-washing”) in-between washes. That way you won't be harming your hair with sulfates, which are found in most shampoos.[1] Keep in mind that co-washing is great for retaining moisture but only mildly cleanses the hair.
Answer:
11 ounces
Step-by-step explanation:
Unpeeled = X
Peeled = (1 - 1/12)X = (11/12)X
X = (11/12)X + (11/12)
X - (11/12)X = 11/12
(1/12)X = 11/12
X = 11 ounces
The answer is B. Because there are 8 ribbons in all. 1 ribbon is black. so the equation would be 1/8. Assuming you don't draw the black ribbon on the first try, then you would try again. The second time you draw a ribbon you don't put the ribbon you drew back in. That means there are only 7 ribbons the second time. The 1 black ribbon is still in the bag than the equation would be 1/7. Then you add the two together. So it would be 1/8 + 1/7 = 1/15. Remember to only add the bottom numbers. not the top ones unless they are different colors or objects.
