rewona [7]

Answer:

The mean of the sampling distribution of x is 0.5 and the standard deviation is 0.083.

Step-by-step explanation:

The Central Limit Theorem estabilishes 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.

For the population, we have that:

Mean = 0.5

Standard deviaiton = 0.289

Sample of 12

By the Central Limit Theorem

Mean = 0.5

Standard deviation s = \frac{0.289}{\sqrt{12}} = 0.083

The mean of the sampling distribution of x is 0.5 and the standard deviation is 0.083.

A shopkeeper bought 775 kg of wheat . He wants to divide all the wheat into 8 bags of the same size. How much Wheat Can he store
Arturiano [62]

In order to calculate how much wheat will be stored in each bag, let's divide the total amount of wheat by the number of bags:

\frac{775}{8}=96.875

Assuming that the amount of wheat each bag can hold is a whole number, so each bag can hold 96 kg (otherwise, each bag would hold 96.875 kg and there would be no wheat left).

Then, to find how much wheat will be left, let's calculate how much the 8 bags will hold, and then we subtract this value from the total:

\begin{gathered} 96\cdot8=768 \\  \\ 775-768=7 \end{gathered}

So there will be 7 kg left.
