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:

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

Which set of numbers represents a Pythagorean triple

Anuta_ua [19.1K]

Answer:

27,36,45

Step-by-step explanation:

Pythagorean theorem

$a^{2} +b^{2} =c^{2}$

$6^{2}+ 9^{2}\\ =117\\\neq 12^{2}$

$7^{2}+ 10^{2}\\ =149\\\neq 12^{2}$

$16^{2}+ 18^{2}\\ =580\\\neq 25^{2}$

$27^{2}+ 36^{2}\\ =2025\\= 45^{2}$
