Answer:
The interval estimate for the population proportion of American adults who got their health insurance from an employer is (0.43, 0.47).
Step-by-step explanation:
The confidence interval is the interval estimate of the population parameter.
The confidence interval has a certain probability that the true value of the parameter is contained in the interval.
The general form of the confidence interval is:
Here,
SS = sample statistic.
MOE = margin of error
The sample statistic is an unbiased estimator of the population parameter. If the sample size is large enough then the sample statistic can be used to estimate the population parameter value.
In this case the parameter of interest is the population proportion of American adults who got their health insurance from an employer.
The information provided is:
<em>SS = p = </em>0.45.
<em>MOE</em> = 0.02.
Compute the confidence interval for the population proportion <em>p</em> as follows:
Thus, the interval estimate for the population proportion of American adults who got their health insurance from an employer is (0.43, 0.47).
9x+27+15x
24x+27
Nine times x equals nine x. Then nine times three equals twenty-seven. Combine nine x and fifthteen x and you get twenty-four x.
Answer:
y = 2(x + 3) + (-2) is the required equation.
Step-by-step explanation:
Here the given points are A( -1,2) and B(-3-2)
Now, slope of the equation =
Hence, the slope of the equation is m = 2
Now, by POINT SLOPE FORMULA:
The equation of a line with slope m and point (x0, y0) is given as
(y - y0) = m (x -x0)
So, here the equation of line with (-3, -2) is
y - (-2) = 2 (x - (-3))
or, y + 2 = 2(x + 3)
⇒ y = 2(x + 3) + (-2) is the required equation.
