Find a 75% confidence interval for the population average weight μ of all adult mountain lions in the specified region. (Round y

kupik [55]

Answer:

75% confidence interval is 91.8±16.66. That is between 75.1 and 108.5 pounds.

Step-by-step explanation:

The question is missing. It is as follows:

Adult wild mountain lions (18 months or older) captured and released for the first time in the San Andres Mountains had the following weights (pounds): 69 104 125 129 60 64

Assume that the population of x values has an approximately normal distribution.

Find a 75% confidence interval for the population average weight μ of all adult mountain lions in the specified region. (Round your answers to one decimal place.)

75% Confidence Interval can be calculated using M±ME where

M is the sample mean weight of the wild mountain lions ( $\frac{69 +104 +125 +129+60 +64}{6} =91.8$ )

ME is the margin of error of the mean

And margin of error (ME) of the mean can be calculated using the formula

ME= $\frac{t*s}{\sqrt{N} }$ where

t is the corresponding statistic in the 75% confidence level and 5 degrees of freedom (1.30)

s is the standard deviation of the sample(31.4)

N is the sample size (6)

Thus, ME= $\frac{1.30*31.4}{\sqrt{6} }$ ≈16.66

Then 75% confidence interval is 91.8±16.66. That is between 75.1 and 108.5

Which expression is equivalent to 4√24x∧6y÷ 128x∧4y∧5

LenKa [72]

Answer:

Option D. $\sqrt[4]{\frac{3x^{2}}{2y}}$

Step-by-step explanation:

$\sqrt[4]{\frac{24x^{6}y}{128x^{4}y^{5}}}$

$\sqrt[4]{(\frac{24}{128})\times (\frac{x^{6}}{x^{4}})\times (\frac{y}{y^{5}})}$

= $\sqrt[4]{(\frac{3}{16})\times {(x)^{6-4}}\times{(y)^{1-5}}}$

= $\sqrt[4]{(\frac{3}{16})\times x^{2}y^{-4}}$

= $\sqrt[4]{\frac{3}{(2)^{4}}\times x\times y^{-4}}$

= $\sqrt[4]{(3\times x^{2)\times (\frac{y^{-1}}{2})^{4}}}$

= $\frac{y^{-1}}{2}\sqrt[4]{3x^{2}}$

= $\sqrt[4]{\frac{3x^{2}}{2y}}$

Option D. $\sqrt[4]{\frac{3x^{2}}{2y}}$ is the correct answer.
