In a survey of 3474 adults aged 57 through 85​ years, it was found that 88.3​% of them used at least one prescription medication. Complete parts​ (a) through​ (c) below. a. How many of the 3474 subjects used at least one prescription​ medication?

Step-by-step explanation:

(1)  Find alpha (α) = 10%  or 0.10

(2)  Find (α/2) = 5% or 0.05

(3)  Subtract 0.05 from 1.0000 to get 0.9500

So the interval of a 90% confidence interval is from 0.0500 < p < 0.9500

Find zα/2 at 0.9500 from z-score normal distribution table yielding z = 1.65

Using z-values →    -1.65 < z < 1.65

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
