Answer:
50%
Step-by-step explanation:
Out of the 200 total people, 100 of them are not boys (the only people on this table who are not boys are girls) so the probability is 100 / 200 = 1 / 2 = 50%.
<span>The volume of each celluloid die is (.25 x .25 x .25) = 0.015625 cubic inch.
To manufacture 24,000 of them, you need to start with <u>at least</u>
(24,000) x (0.015625) = <u>375 cubic inches</u>.
I don't know how celluloid is sold, so you should also keep in mind that
375 cubic inches = about 207.8 fluid ounces, or about 6.5 quarts.
I'm sure a bit more than that was used in the manufacture, since
there's always some wasted, spilled, or trimmed off of the edges. </span>
The quotient is 215.
3870/18= 215. The answer of two divided numbers is called the quotient
Answer:
The 90% confidence interval for the population mean is (300.78, 315.22).
Step-by-step explanation:
We have to calculate a 90% confidence interval for the mean.
The population standard deviation is know and is σ=17.
The sample mean is M=308.
The sample size is N=15.
As σ is known, the standard error of the mean (σM) is calculated as:
The z-value for a 90% confidence interval is z=1.645.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 90% confidence interval for the population mean is (300.78, 315.22).
