The diameter of a sphere is 6ft 6in. Find the radius
storchak [24]

<u>Answer: </u>

The diameter of a sphere is 6ft 6in. The radius of sphere is 3 feet 3 inches.

<u>Solution: </u>

Given that the diameter of sphere is 6 feet 6 inches.  

We have to find the radius of the sphere.

The relation between diameter and radius of sphere is given as  

\text { diameter }=2 \times \text {radius}

Therefore, radius=\frac{\text {diameter}}{2}

radius=\frac{6 \text { feet } 6 \text { inches }}{2}

Radius = 3 feet 3 inches.

Hence the radius of the sphere is 3 feet 3 inches.

The mean per capita consumption of milk per year is 131 liters with a variance of 841. If a sample of 132 people is randomly sel
Inessa [10]

Answer:

0.8389 = 83.89% probability that the sample mean would be less than 133.5 liters.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

The mean per capita consumption of milk per year is 131 liters with a variance of 841.

This means that \mu = 131, \sigma = \sqrt{841} = 29

Sample of 132 people

This means that n = 132, s = \frac{29}{\sqrt{132}}

What is the probability that the sample mean would be less than 133.5 liters?

This is the p-value of Z when X = 133.5. So

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

By the Central Limit Theorem

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

Z = \frac{133.5 - 131}{\frac{29}{\sqrt{132}}}

Z = 0.99

Z = 0.99 has a p-value of 0.8389

0.8389 = 83.89% probability that the sample mean would be less than 133.5 liters.
