Answer:
(0.102, -0.062)
Step-by-step explanation:
sample size in 2018 = n1 = 216
sample size in 2017 = n2 = 200
number of people who went for another degree in 2018 = x1 = 54
number of people who went for another degree in 2017 = x2 = 46
p1 = x1/n1 = 0.25
p2 = x2/n2 = 0.23
At 95% confidence level, z critical = 1.96
now we have to solve for the confidence interval =
<h2>= 0.02 ± 1.96 * 0.042
= 0.02 + 0.082 = <u>0.102</u>
= 0.02 - 0.082 = <u>-0.062</u>
<u>There is 95% confidence that there is a difference that lies between - 0.062 and 0.102 on the proportion of students who continued their education in the years, 2017 and 2018.</u>
<u></u>
<u>There is no significant difference between the two.</u>
Answer: 545,846,230
Step-by-step explanation: To round 545,846,229 to the nearest ten, we first find the digit in the rounding place which in this case is 2 in the tens place.
Next, look at the digit to the right of the rounding place which in this case is 9. The rules of rounding tell us that if the digit to the right of the rounding place is less than 5, we round down but if the digit to the right of the rounding place is greater than or equal to 5, we round up.
In this problem, since 9 is greater than or equal to 5, we round up. This means we add 1 to the digit in the rounding place so 2 becomes 3 and we change all digits to the right of the rounding place to 0.
Therefore, 545,846,229 rounded to the nearest 10 is 545,846,230.
