Sorry, if I did wrong, I'm in middle school so its a bit ahrd.
The interval of true average price of a regular room with a king size bed in the resort community with 99% confidence is ( 14.74, 48.89 ).
<h3>What is the confidence interval of an average?</h3>
One method of determining the actual population mean is by using a confidence interval for the mean. A confidence interval provides a lower estimate and an upper estimate rather than just the mean.
A confidence interval expresses the degree of uncertainty surrounding a given statistic. A margin of error is frequently used with confidence intervals. It reveals the degree to which you may be certain that the findings of a poll or survey correspond to what you would anticipate discovering if it were possible to poll the complete population. Levels of confidence are inextricably linked to confidence intervals.
x = mean;
99% confidence interval for μ is
(x - t * S) /√n < μ <( x + t * S) /√n;
(135 - 2.898 * 25 )/√18 < μ < (135 + 2.898 * 25)/√18;
14.74< μ< 48.89;
99% CI is ( 14.74, 48.89 ) ;
critical value at 0.01 significance level with 17 df = 2.898

Find slope of line
goes up -4 units and goes 2 units to left, -4/2=-2
y=-2x+b
where does it hit y axis? at y=3
y=-2x+3
ok so line of inequality is dotted
see a point in that shaded area
(3,0)
0=-2(3)+3
0=-6+3
0=-3
false
but
0>-3 is true, so
y>-2x+3 is the equaiton
