In the week before and the week after a holiday there were 10,000 total deaths and 4968 of them occurred in the week before the

holiday.
a) construct a 90% confidence interval estimate of the proportion of deaths in the week before the holiday to the total death in the week before and the week after the holiday

b) based on the result does there appear to be any indication that people can temporarily postpone their death to survive the holiday

THIS MAY HELP YOU

CI = mean proportion ± (z*)sqrt[ (p)(1-p) / n]
where z* = 1.645 with 10%/2 = 0.05 area in each tail mean proportion p = 4946 / 10000 = 0.4946 now fill in the values from the problem ...
 CI = mean proportion ± (z*)sqrt[ (p)(1-p) / n]
 CI = 0.4946 ± (1.645)sqrt[ (0.4946)(1- 0.4946) / 10000]
 CI = (0.4864, 0.5028)

1) write a system on equations with the solution (2, -3). Work the problem out using the substitution method
solmaris [256]

The system of the equations that have the solution of (2, -3) are given below.

3x + 2y = 0 and 3y = 2x - 13

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Write a system of equations with the solution (2, -3).

From a single point, an infinite number of lines pass through this point.

Let one line is passing through the origin. Then the equation of the line will be

\rm y  = \dfrac{-3}{2} (x)\\\\y = -1.5x

And the other line is perpendicular to the line which is passing through the origin and a point (2, -3).

\rm y = \dfrac{2}{3} x + c

Then this line also passes through a point (2, -3). Then the value of c will be

\rm -3 = \dfrac{2}{3} \times 2 + c\\\\c \ \  = -13

Then the equation of the line will be

3y = 2x -13
