The US Department of Health and Human Services wants to know whether the national healthcare system is achieving its goals in Vi

rginia. Much information about healthcare comes from patient records, but that source doesn't allow us to compare people who use health services with those who don't. Therefore, the US Department of Health and Human Services conducted the Virginia Health Survey, which was used to interview a random sample of 65,439 people who live in the state of Virginia. Part A: What is the population for this sample survey? What is the sample? (4 points) Part B: The survey found that 71% of males and 88% of females in the sample had visited a general practitioner at least once during the past year. Do you think these estimates are close to the truth about the entire population? Explain. (6 points) (10 points)

Answer:

A: The population of Virginia is the population, and the sample is the 65,439 people who were interviewed for the survey.

B: I think that these approximations are close the that of the entire population. This is because the surveyor randomly interviewed people in the population to create the sample. This means that there is no apparent bias in the experiment, which means that it is probable that the sample reflects the population

Function A and Function B are linear functions. Compare the two functions and choose all that are correct.
Olegator [25]

Answer:

  2 .The slope of Function A is less than the slope of Function B

Step-by-step explanation:

A graph of Function A shows it has a y-intercept of 4, the same as that of Function B. (Statements 3 and 4 are not correct.)

The slope of Function A is 2, which is less than the slope of 3 that Function B has. (Statement 2 is correct; statement 1 is not.)

_____

<em>More detailed working</em>

The slope of Function A can be figured easily between the points with x-values that differ by 1:

  m = (y3 -y2)/(x3 -x2) = (24-22)/(10-9) = 2/1 = 2 . . . . . Fun A has slope of 2.

The slope of Function B is the coefficient of x in the equation: 3.

__

The y-intercept of Function A can be found starting with point-slope form:

  y -22 = 2(x -9)

  y = 2x -18 +22

  y = 2x +4 . . . . . . . slope-intercept form

The intercept of +4 is the same as that of Function B.

If the probability of surviving a head on car accident at 55 mph is 0.097, then what is the probability of not surviving
BabaBlast [244]

The probability of not surviving a head-on car accident is: 0.903

Step-by-step explanation:

The probabilities of occurrence and non-occurrence of an event add up to one.

If p is the probability that an even will happen and q is the probability that it will not happen

Then

p+q=1

Here,

Probability of surviving = p = 0.097

Probability of not surviving = q = ?

0.097 + q = 1\\q = 1 - 0.097\\q = 0.903

The probability of not surviving a head-on car accident is: 0.903

Janet makes homemade dolls. Currently, she produces 23 dolls per month. If she increased her production by 18%, how many dolls w
SCORPION-xisa [38]

Answer:

First, calculate 18% of 23.

23 x 0.18 = 4.14

Then, add this value (the increase) to the original value of 23.

23 + 4.14 = 27.14

Rounding off, we get 27.
