High blood pressure has been identified as a risk factor for heart attacks and strokes. The National Health and Nutrition Examination Survey reported that the proportion of U. S. adults with high blood pressure is 0.3. A sample of 38 U. S. adults is chosen. (a) Is it appropriate to use the normal approximation to find the probability that more than 40% of the people in the sample have high blood pressure? If so, find the probability. If not, explain why not. (b) A new sample of 80 adults is drawn. Find the probability that more than 40% of the people in this sample have high blood pressure. (c) Find the probability that the proportion of individuals in the sample of 80 who have high blood pressure is between 0.23 and 0.32.

answer: 25 is the correct answer

step-by-step explanation:

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
