<span>The standard error of a distribution of sample proprtions is defined as the standard deviation of the distribution and is symbolized by
and is calculated by the formula
</span>.
Given a <span>random
sample of n = 800 observations and a sample proportion
p = 0.44.
To test:
The
standard error rounded to four decimal places is given by:
</span>
Step-by-step explanation:
Part A:
car 1 => exponential function
car 2=> linear function
Part B:
car 1 => the function f(x) = 45,000 • (0.9)^x
car 2= > the function f(x) = 45,000 - (3,000)x
Part C:
after 13 years, the value of :
car 1 => 45,000 • (0.9)^13 = $ 11,438.40
car 2=> 45,000 - (3,000)(13) = $ 6,000
the difference is = 11,438.40 - 6,000
= $ 5,438.40
its better to Belinda to purchase car 1.
