The National Center for Education Statistics surveyed 4400 college graduates about the lengths of time required to earn their bachelor’s degrees. The mean was 5.15 years, and the standard deviation was 1.68 years. Based on the above information, construct a 98% confidence interval for the mean time required to earn a bachelor’s degree by all college students. In your work state the type of interval you used (t or z), the mean, the standard deviation, and sample size and confidence level.  Round to 2 decimal places 

A bottling company uses a filling machine to fill plastic bottles with a popular cola. The bottles are supposed to contain 300 milliliters (ml). In fact, the contents vary according to a normal distribution with mean µ=303 ml and standard deviation σ= 4 ml. When showing your work indicate what you put in the calculator for the mean, the standard deviation, the lower limit and the upper limit. Round to 4 decimal placesWhat is the probability that an individual bottle contains less than 299 ml?What is the probability that the sample mean of 36 bottles is less than 301 mil?

A random sample of 58 life insurance policy holders showed that the average premiums paid on their life insurance policies was $342 per year with a standard deviation of $62. Make a statement about this interval in context of the problem. In your work state the type of interval you used (t or z), the mean, the standard deviation, and sample size and confidence level.  Round to 2 decimal placesConstruct a 90% confidence interval for the population mean. What is the definition of the central limit theorem?
