The mean of the sampling distribution of the means is equal to the population mean.

The mean of the sampling distribution of the means is less than the population mean.

The mean of the sampling distribution of the means is greater than the population mean.

The means of the samples drawn from a population may be equal, greater than, or less than the population mean.

A certain population has a mean of 15.4 and a standard deviation of 5.6. If random samples of size 5 are taken from this population, which of the following statements is correct?

The mean of the sampling distribution of the sample means is equal to 15.4.

The mean of the sampling distribution of the sample means is less than 15.4.

The standard deviation of the sampling distribution of the sample means is 5.6.

The standard deviation of the sampling distribution of the sample means is 15.4.

The world is now facing a COVID-19 pandemic, an infectious disease that can be prevented by frequently washing your hands and by avoiding close contact with people who are sick. About a decade ago, a similar disease was experienced which was named severe acute respiratory syndrome (SARS). It is recorded that the average age of those infected is 32.6 years old with a standard deviation of 3.7 years. If 50 samples are to be chosen, what would be the sample's mean and standard deviation?

Mean = 32.6 years old, Standard Deviation = 0.52 years

Mean = 32.6 years old, Standard Deviation = 3.7 years

Mean = 4.61 years old, Standard Deviation = 3.7 years

Mean = 4.61 years old, Standard Deviation = 0.52 years

A population has a mean of 1000 and a standard deviation of 72. A random sample of 100 students is drawn from this population. Compute its mean and standard deviation.

$$\mu_{\overline{x}}=1000$$ and $$\sigma_{\overline{x}}=7.2$$

$$\mu_{\overline{x}}=10$$ and $$\sigma_{\overline{x}}=0.72$$

$$\mu_{\overline{x}}=1000$$ and $$\sigma_{\overline{x}}=0.72$$

$$\mu_{\overline{x}}=1000$$ and $$\sigma_{\overline{x}}=72$$

A random sample of $$n=60$$ measurements is obtained from a population with $$\mu=198$$ and $$\sigma=23$$ . Describe the sampling distribution of sample means by computing $$\mu_{\overline{x}}$$ and $$\sigma_{\overline{x}}$$ . Solve for $$\mu_{\overline{x}}$$ and $$\sigma_{\overline{x}}$$ .

$$\mu_{\overline{x}}=198$$ and $$\sigma_{\overline{x}}=2.97$$

$$\mu_{\overline{x}}=198$$ and $$\sigma_{\overline{x}}=23$$

$$\mu_{\overline{x}}=25.56$$ and $$\sigma_{\overline{x}}=23$$

$$\mu_{\overline{x}}=25.56$$ and $$\sigma_{\overline{x}}=2.97$$

Which of the following statements is TRUE?

The graph of the population approaches normal distribution as the number of sample gets higher.

Central Limit Theorem cannot be applied if the graph is asymmetrical.

Central Limit Theorem is not applicable if the initial probability distribution function is not increasing or decreasing.

If the number of sample is less than or equal to 5, Central Limit Theorem is not applicable.

Which of the following relationship is NOT true?

As the number of sample size increases, the samples mean decreases.

As the number of sample size increases, the margin of error decreases.

As the number of sample size increases, the standard deviation increases.

As the number of sample size increases, the width of the confidence interval decreases.
