Use the table to write a linear function that relates Y to X

yan [13]

Answer:

y = 3/4x + 10

Step-by-step explanation:

The equation of a line is y = slope * x + y-intercept

To find the slope, you choose two points and do (y1-y2)/(x1-x2): Point 1 can be (4,13) and point 2 can be (8,16) so, slope = (13-16)/(4-8) = -3/-4 = 3/4

The y-intercept is the value of y when x is 0, so it would be 10.

Put it together and you get y = 3/4x + 10

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. A survey

marta [7]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Sample size = 865 = n

Number of voters favor approval of an issue before the legislature = 408 = x

So, $\hat{p}=\dfrac{x}{n}=\dfrac{408}{865}=0.4716$

At 95% confidence level of significance, z = 1.96

So, confidence interval would be

$\hat{p}\pm z\sqrt{\dfrac{p(1-p)}{n}}}\\=0.4716\pm 1.96\times \sqrt{\dfrac{0.4716\times (1-0.4716)}{865}}}\\\\=0.4716\pm 0.00082222\\\\=(0.4716-0.00082222..,0.4716+0.00082222...)\\\\=(0.471,0.472)$

Hence, option 'c' is correct.
