A data set includes 106 body temperatures of healthy adult humans having a mean of 98.7degreesF and a standard deviation of 0.66

blondinia [14]

Answer:

The 99% confidence intervals are

(98.4346 , 98.7654)

C) This suggests that the mean body temperature could very possibly be 98.6degrees°F.

<u>Step-by-step explanation:</u>

Given data a data set includes 106 body temperatures of healthy adult humans having a mean of 98.7degreesF and a standard deviation of 0.66degreesF

sample size n = 106

Mean of the population ' μ' = 98.7degreesF

standard deviation of population 'σ' = 0.66degreesF

Mean of the sample x⁻ = 98.6degreesF

Level of significance ∝ = 0.99 0r 0.01

<u>Confidence limits :-</u>

The values $(x^{-} - 2.58\frac{S.D}{\sqrt{n} } ,x^{-} +2.58\frac{S.D}{\sqrt{n} } )$ are called 99% of confidence limits

For the mean of the Population corresponding to the given sample.

$(98.6 - 2.58\frac{0.66}{\sqrt{106} } ,98.6 +2.58\frac{0.66}{\sqrt{106} } )$

on calculation, we get

(98.6 - 0.1654,98.6 + 0.1654)

The 99% confidence intervals are

(98.4346 , 98.7654)

C)<u> This suggests that the mean body temperature could very possibly be 98.6degrees°F</u>.

Greeley [361]

<h3>Answer: -14 degrees Fahrenheit</h3>

Explanation:

Draw a vertical number line. At the center is 0. Anything above this marker represents positive temperatures. Anything below 0 is negative. So we'll have -8 below 0. Move 6 spaces down to go from -8 to -14. You can think of it as moving 6 floors down a building to go from basement level 8 to basement level 14.

1/21 * 1/20 = 1/420 that is the probability that you are chosen first.
Probability of your friend chosen first = 1/420 also.

So the required probability = 1/420 + 1/420 = 1/210 Answer

Its D

Usimov [2.4K]

The variable you wanted to find wasn’t mentioned, so I solved for all three:

5xy + n = 12

5xy = 12 - n

x = 12-n/5y

y = 12-n/5x

n = 12 - 5xy
