Answer:

The 95% confidence interval estimate of the proportion of people who say that they voted

(0.67122 , 0.72798)

Step-by-step explanation:

Step(i):-

In a recent survey of 1002 people, 701 said that they voted in a recent presidential election.

Sample proportion

$p = \frac{x}{n} = \frac{701}{1002} = 0.6996$

Step(ii)

The 95% confidence interval estimate of the proportion of people who say that they voted

$(p^{-} - Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{p(1-p)}{n} } )$

$(0.6996 - 1.96\sqrt{\frac{0.6996(1-0.6996)}{1002} } , 0.6996 + 1.96 \sqrt{\frac{0.6996(1-0.6996)}{1002} } )$

(0.6996 - 1.96 X 0.01448 , 0.6996 + 1.96 X 0.01448)

(0.6996 - 0.02838 , 0.6996 + 0.02838)

(0.67122 , 0.72798)

Final answer:-

The 95% confidence interval estimate of the proportion of people who say that they voted

(0.67122 , 0.72798)

A landscaper has a total of $800 to spend on bushes at $20 each and trees at $50 each

NemiM [27]

Answer:

x=40 y=16

Step-by-step explanation:

20x+50y=800 you can turn it into slope-intercept form and it would end up being y=-2/3x+16 so now you have your y intercept (16) and you know your rise and run -2(rise)3(run).

Or you can substitute a zero for x and solve for y

20(0)+50y=800 which equals 50y=800 which equals 16 y=16

then you substitute a zero for y and solve for x

20x+50(0)=800 which equals 20x=800 which equals 40 x=40

Question 5 When studying the population of blue jays, only a sample of blue jay population was measured. Why would just a sample

Firlakuza [10]

Only a sample of the blue jay population was measured because it would be impossible to measure the entire population. The population of blue jays is all of the blue jays in the world. It would not be possible to measure all of them.
