Assume that the population of human body temperatures has a mean of 98.6 degrees F and a standard deviation of 0.62 degrees F. I

dimulka [17.4K]

Answer:

0% probability of getting a mean temperature of 98.2 degrees F or lower.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$ .

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 98.6, \sigma = 0.62, n = 106, s = \frac{0.62}{\sqrt{106}} = 0.06$

Find the probability of getting a mean temperature of 98.2 degrees F or lower.

This is the pvalue of Z when X = 98.2. So

$Z = \frac{X - \mu}{s}$

$Z = \frac{98.2 - 98.6}{0.06}$

$Z = -6.67$

$Z = -6.67$ has a pvalue of 0.

So there is a 0% probability of getting a mean temperature of 98.2 degrees F or lower.

Will give brainliest PLs help Here is the argument you are presenting: There is a need for students to understand and be able to

Natasha2012 [34]

1. It is easier to apply it to real-world situations once you have learned to construct geometric figures using compasses and straightedges.

2. Constructing geometric figures yourself also helps you understand the material and learn easily.

3. There is more accuracy and it is easier to prove your accuracy in your own constructions.

I hope this helps :)

Insert commas suitably and write the names according to International system of numeration: a) 40050017 b) 251400

kobusy [5.1K]

Answer:

a) 40050017 = 40,050,017

Forty million fifty thousand and seventeen

b) 251400 = 251,400

Two hundred fifty one thousand and four hundred

Step-by-step explanation:

In international system commas are placed after three digits starting from the unit's place.

a) 40050017 = 40,050,017

Forty million fifty thousand and seventeen

b) 251400 = 251,400

Two hundred fifty one thousand and four hundred

It can be placed as shown below.
