Step-by-step explanation:
Answer:
d. (0.737, 0.823)
The 90% confidence interval is = (0.737, 0.823)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
p+/-z√(p(1-p)/n)
Given that;
Proportion p = 195/250 = 0.78
Number of samples n = 250
Confidence interval = 90%
z value(at 90% confidence) = 1.645
Substituting the values we have;
0.78 +/- 1.645√(0.78(1-0.78)/250)
0.78 +/- 1.645√(0.0006864)
0.78 +/- 1.645(0.026199236630)
0.78 +/- 0.043097744256
0.78 +/- 0.043
(0.737, 0.823)
The 90% confidence interval is = (0.737, 0.823)
The answer simplified is 56 !!
It appears the question is asking you to make mathematical statements.
Basically, just find a way to use the numbers above to make your own addition and subtraction problems.
ADDITION
2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
SUBTRACTION
9.57 - 7.1 = 2.47
9.57 - 2.47 = 7.1
