When obtaining a confidence interval for a population mean in the case of a finite population of size N and a sample size n whic

Elanso [62]

Answer:

95% Confidence interval for the mean

$142.8 \leq\mu\leq158.4$

Step-by-step explanation:

We have to calculate a 95% confidence interval for the mean of a finite population.

The error is multiplied by the following finite population correction factor:

$cf=\sqrt{\frac{N-n}{N-1} }$

The standard deviation can be estimated as

$\sigma=\frac{s}{\sqrt{n}} \sqrt{\frac{N-n}{N-1} } =\frac{24.4}{\sqrt{32} }* \sqrt{\frac{200-32}{200-1} }=3.963$

The 95% confidence interval has a z value of 1.96, so it becomes:

$M-z*\sigma_c\leq\mu\leq M+z*\sigma_c\\\\150.6-1.96*3.963\leq\mu\leq 150.6+1.96*3.963\\\\ 142.8 \leq\mu\leq 158.4$

A homes value increases at an average rate of 5.5% each year the current value it is $120,000 what function can be used to find

likoan [24]

Around this time many people find home prices going up dramatically. Let's start with the X factor. If we know the starting is $120,000, the we know the initial velocity. To find the final but the very simple equation one may use is; P=(120000)^x\0.5

a delivery truck is carrying and 8713 lb load of pet food. At a weighing station, the loaded truck weighs 17200 lb. What is the

netineya [11]

We know that the load is 8713 lbs.

The total weight (truck + load) is 17200 lb.

Then, we can calculate the weight of the empty truck as:

$\begin{gathered} L=8713 \\ W=L+T=17200 \\ \Rightarrow T=W-L \\ T=17200-L=17200-8713=8487 \\ \end{gathered}$

Answer: the empty truck's weight is 8487 lb.

T: empty truck's weight

W: total weight (loaded truck's weight)

L: Load

The equation is:

T = W - L
