Answer:5y=x-35
Step-by-step explanation:
The given line passes through the points ,
.
Let the slope of the line be .
If a line passes through and
,then
So,
Y-intercept of a line is defined as the y-coordinate of the point where the line touches y axis.
Let the y intercept be
From the graph,
The equation of the line with slope and y-intercept
is
So,
The probability that the sample proportion is within ± 0.02 of the population proportion is 0.3328
<h3>How to determine the probability?</h3>The given parameters are:
Start by calculating the mean:
Calculate the standard deviation:
Within ± 0.02 of the population proportion are:
Calculate the z-scores at these points using:
So, we have:
The probability is then represented as:
P(x ± 0.02) = P(-0.43 < z < 0.43)
Using the z table of probabilities, we have:
P(x ± 0.02) = 0.3328
Hence, the probability that the sample proportion is within ± 0.02 of the population proportion is 0.3328
