Question:

A population has a mean of 150 and a standard deviation of 21. If a random sample of 49 is taken, what is the probability that the sample mean is:

  1. less than 147
  2. between 152.5 and 157.5
  3. between 148 and 158?

Question 2 

A random sample of 81 is drawn from a population with a standard deviation of 12. If a sample mean greater than 300 is obtained only 18% of the time, what is the mean of the population?

Question 3

For a population with p=0.6, find the probability for each sample proportion and given sample size.

  1. n = 100 and
  2. n = 240 and

Question 4

A population proportion is .32. Suppose a random sample of 40 items is sampled randomly from this population. What is the probability that the sample proportion is:

  1. between .18 and .51
  2. between .38 and .48

Question 5

According to a study undertaken in a large rural town, 15% of children aged from 10 to 16 years old were found to exercise less than one hour per day. If a random sample of 35 children in this age group was selected from this town, what is the probability that more than 7 children would be found to exercise less than one hour per day?

Question 6 

According to a study, the average travel time to work in Perth is 27.4 minutes. A business researcher wants to estimate the average travel time to work in Brisbane using a 95% level of confidence. A random sample of 45 Brisbane commuters is taken and the travel time (minutes) to work is obtained from each. The data follow. Assuming a population standard deviation of 5.124 minutes, compute a 95% confidence interval on the data. What is the point estimate and what is the margin of error of the interval? Explain what these results mean in terms of Perth commuters.
