Answer from: Gattuso

For this case from the info given we have the estimated proportion of people who thinks that Children of illegal inmigrants should be able to attend public school

So then the value reported 45% or in fraction 0.45 represent the sample proportion fo interest.

$\hat p =\frac{X}{n}=0.45$

And this value was calculated with a sample of n =1000 people.

And X for this case is 450, because 0.45*1000=450

The real interest is on the population proportion of people who thinks that Children of illegal inmigrants should be able to attend public school

Step-by-step explanation:

Assuming the following question : "Give the relevant proportion using correct notation. Your answer should be an expression composed of symbols: A recent headline states that 45% Think Children of illegal inmigrants Should Be Able to Attend Public School. The report gives the results of a survey of 1000 randomly selected likely voters in the US."

Answer from: Quest

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean = $\frac{2+3+4+5+6+7+8+9}{8}=\frac{44}{8}=5.5$

also, median= $\frac{5+6}{2}=\frac{11}{2}=5.5$ , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean = $\frac{2+3+4+5+6}{5}=\frac{20}{5}=4$

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
