Answer:

The probability that the difference between the sample mean $\bar{x}$ and the true population mean $\mu$ is : $P[|\bar{x}-\mu|\leq0.7]=0.9876$

Step-by-step explanation:

Given :

Population standard deviation $\sigma=2.8$ .

Sample size $n=100$

The sample mean standard deviation $=\frac{\sigma}{\sqrt{n}}$

To find :

The probability that the difference between the sample mean $\bar{x}$ and the true population mean $\mu$

$\because\frac{\sigma}{\sqrt{n}}=\frac{2.8}{\sqrt{100}}=\frac{2.8}{10}=0.28$

Now, the probability that the difference between the sample mean $\bar{x}$ and the true population mean $\mu$ is :

$P[|\bar{x}-\mu|\leq0.7]$ , $n$ is large $\Rightarrow \frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}=z$

$\Rightarrow P[\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}$

$\Rightarrow P[z$

$\Rightarrow P[-2.5$

Therefore, the probability $P[|\bar{x}-\mu|\leq0.7]=0.9876$
