Answer: aA 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years = (0.163,0.189)
Step-by-step explanation:
Let p = population proportion of adults in the U.S. who have donated blood in the past two years.
Given: A Gallup survey of 2322 adults (at least 18 years old) in the U.S. found that 408 of them have donated blood in the past two years.
Sample size: n= 2322
Sample proportion
Critical z-value for 90% confidence level : z*=1.645
The confidence interval for population proportion:
A 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years:
Hence,
Answer:
Rational, Rational, Rational, Irrational, Irrational
Step-by-step explanation:
The first question:
- -√49
- -7
This number is rational
Second:
- -70.8888....
This number is rational. It wouldn't be rational if the digits won't repeat.
Third:
- 15.91
This number is rational
Fourth:
- 17π
This is irrational. The digits of pi do not repeat, making it irrational.
Fifth:
- -√14
Irrational. The square root of a non-perfect square is irrational.

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut point with the "y" axis
We have, according to the data provided, that the line is of the form:
That means that the slope is -1.
