1.) What is we draw a sample of 225 people from a population with the mean age of 40 and the standard deviation of 24:

1.) What is the probability of getting a sample mean of 38.2 or lower ?

2.) What is the probability of getting a sample mean of 44.5 or higher ?

3.) What is the probability of getting a sample mean between 38.2 and 44.5 ?

A random sample of size n = 225 is taken from a population with a population proportion P = 0.55. [You may find it useful to reference the z table.] a. Calculate the expected value and the standard error for the sampling distribution of the sample proportion. (Round "expected value" to 2 decimal places and "standard error" to 4 decimal places.) b. What is the probability that the sample proportion is between 0.50 and 0.60? (Round “z” value to 2...

Many statistical procedures require that we draw a sample from a population whose distribution is approximately normal. Often we don’t know whether the population is approximately normal when we draw the sample. So the only way we assess whether the population is approximately normal is to examine its sample. Assessing normality is more important for small samples. Below, you’ll see some small samples and you’ll be asked to assess whether the populations they are drawn from can be treated as...

From a random sample from normal population, we observed sample mean=84.5 and sample standard deviation=11.2, n = 16, H0: μ = 80, Ha: μ < 80. State your conclusion about H0 at significance level 0.01. choices: A. Test statistic: t = 1.61. P-value = 0.9356. Reject the null hypothesis. There is sufficient evidence to conclude that the mean is less than 80. The evidence against the null hypothesis is very strong. B. Test statistic: t = 1.61. P-value = 0.0644. Do...
