The proportion of students that got the recommended amount of sleep is 0.179.
<h3>What is a proportion?</h3>
A proportion can be defined as an expression which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.
<h3>How to calculate proportion of students that got the recommended amount of sleep?</h3>
Since the total number of students in this class is 28, we would develop an expression to relate the number of students that sleep at least for 5 hours per night:
Proportion = 5/28
Proportion = 0.179.

One of the survey questions was “How much sleep did you get last night?” Here is a dotplot of the data: Experts recommend that high school students sleep at least per night. What proportion of students in this class got the recommended amount of sleep? Amount of sleep (h) (Round your answer to three decimal places.)
1 and 3 are correct, this is due to the fact that modern technology is constantly growing and other developed nations are feeling threatened or inferior when another developed nation grows further ahead. National security has also grown global, just the threat of a foreign country developing nuclear capability is enough for another country to launch missle strikes or other acts in order to quell the threat of another nuclear capable country. 2 is not correct because industrial strategies are being shared throughout the world constantly and the safety of a country no longer stands by their standing army or navy, but by the threat of nuclear capability or a possibility of retaliation through explosive nature. Even today, most wars are done through the army holding down a line, and the navy/airforce launching long ranged missile attacks of various nature.
Answer:
it is fertilization I took the test
Answer:
The sampling distribution of the mean will have no unit.
Explanation:
Given that:
P(B) = 0.62
P(C) = 0.71
pˆB = 0.70
pˆC = 0.75
The expression : pˆB−pˆC
Represents the difference in mean of the sample distribution :
The proportions pˆB = 0.70 and pˆC = 0.75 are obtained as (number of workers who purchased coffee / total number of workers). The ratio above due to division will have no units.
