The amount of lateral expansion (mils) was determined for a sample of n = 8 pulsed-power gas metal arc welds used in LNG ship co

Alona [7]

Answer:

95% Confidence interval for the variance:

$3.6511\leq \sigma^2\leq 34.5972$

95% Confidence interval for the standard deviation:

$1.9108\leq \sigma \leq 5.8819$

Step-by-step explanation:

We have to calculate a 95% confidence interval for the standard deviation σ and the variance σ².

The sample, of size n=8, has a standard deviation of s=2.89 miles.

Then, the variance of the sample is

$s^2=2.89^2=8.3521$

The confidence interval for the variance is:

$\dfrac{ (n - 1) s^2}{ \chi_{\alpha/2}^2} \leq \sigma^2 \leq \dfrac{ (n - 1) s^2}{\chi_{1-\alpha/2}^2}$

The critical values for the Chi-square distribution for a 95% confidence (α=0.05) interval are:

$\chi_{0.025}=1.6899\\\\\chi_{0.975}=16.0128$

Then, the confidence interval can be calculated as:

$\dfrac{ (8 - 1) 8.3521}{ 16.0128} \leq \sigma^2 \leq \dfrac{ (8 - 1) 8.3521}{1.6899}\\\\\\3.6511\leq \sigma^2\leq 34.5972$

If we calculate the square root for each bound we will have the confidence interval for the standard deviation:

$\sqrt{3.6511}\leq \sigma\leq \sqrt{34.5972}\\\\\\1.9108\leq \sigma \leq 5.8819$

Answer:

<em><u>The answer is</u></em>: <u>a. 30 year FHA, 3.5% down at a fixed rate of 6.5%.</u>

<u />

Step-by-step explanation:

If Eli wants to pay as little as possible, and we start with a 30-year mortgage, among the percentages that must be paid, <u>the lowest is 3.5%</u>, in terms of the fixed rate, <u>the lowest is 5%</u>, but if we see the amount of <u>30 years, it is 10%</u>, so although the fixed rate of <u>6.5% is higher than that of 5%, the payment is only made once</u>, and the difference is not so much compared to 10% for 30 years.

<em><u>The answer is</u></em>: <u>a. 30 year FHA, 3.5% down at a fixed rate of 6.5%.</u>
